Which statement explains why the bonds between nonmetals tend to be covalent quizlet?
Which statement explains why the bonds between nonmetals tend to be covalent? They have small differences in electronegativity.
Which of these is a typical property of a substance that is composed of atoms that are held together by covalent bonds quizlet?
Which of these is a typical property of a substance that is composed of atoms that are held together by covalent bonds? It does not conduct electricity in any form.
Which statement best explains why a metal atom and a nonmetal atom are most likely to form an ionic bond quizlet?
C. Which statement best explains why a metal atom and a nonmetal atom are most likely to form an ionic bond? Metal atoms have low ionization energy, and nonmetal atoms have high electronegativity, so electrons transfer easily from the nonmetal atom to the metal atom.
What will most likely happen when to bromine atoms bond together?
What will most likely happen when two bromine atoms bond together? The atoms will become less stable. An ionic bond will hold them together.
Why do bonds between nonmetals tend to be covalent?
Atoms form covalent bonds in order to reach a more stable state. A given nonmetal atom can form a single, double, or triple bond with another nonmetal.
Which statement correctly describes what happens to Li and Cl atoms when they bond?
Which statement correctly describes what happens to Li and Cl atoms when they bond? Li loses 1 valence electron and becomes a negative ion, Cl gains 1 valence electron and becomes a positive ion.
Which property best indicates that a compound contains an ionic bond?
The property that best indicates that a compound contains an ionic bond is d. It conducts electricity when molten.
Which property is best to use when determining the strength of an ionic bond?
Which property is best to use when determining the strength of an ionic bond in a solid? A. Lattice energy.
Which characteristic best describes a decomposition reaction?
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
Which statement best describes how an ionic bond forms?
Which statement best describes how an ionic bond forms? The transfer of electrons forms strong bonds between ions. The sharing of electrons forms strong bonds between ions.
Which of the following statements best explains why metals are good conductors of electricity?
Metals are excellent conductors because the atoms in a metal form a matrix through which their outer electrons can move freely. Instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions .
Which statement best explains the factors that affect ionic bond strength in terms of electrostatic energy?
Which statement best explains the factors that affect ionic bond strength in terms of electrostatic energy? Electrostatic energy increases as the magnitude of the oppositely charged ions increases and their separation increases.
Which type of bond will most likely form between Cesium Cs and bromine Br?
Therefore the bond is ionic.
What type of atoms would most likely be held together by molecular covalent bonds?
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Which element attract electrons most strongly in chemical bonds?
Elements with higher electronegativities, such as N, O, and F (fluorine), have a strong attraction for electrons in a chemical bond and will therefore “pull” electrons away from less electronegative atoms. Elements with low electronegativity, such as metals, tend to “give away” electrons easily.
Which description best explains an ionic bonding shares electrons between non-metals molecular bonding donates electrons?
Covalent Bonds vs Ionic Bonds Covalent Bonds Polarity: Low Formation: A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is “strong” enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others.
Do nonmetals form anions or cations?
Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).
What metals make covalent bonds?
For example, beryllium and aluminium are both metals but they bond covalently with chlorine to form beryllium chloride and aluminium chloride respectively.
Which statement about crystal lattice energy is best supported by the information in Table?
Which statement about crystal lattice energy is best supported by the information in the table? The lattice energy increases as cations get smaller, as shown by LiF and KF.
Which statement best describes the basis of the band theory of metallic bonding?
Which statement best describes the basis of the band theory of metallic bonding? –Molecular orbitals overlap to form atomic orbitals in which the valence electrons of the atoms travel. –Molecular orbitals overlap to form atomic orbitals in which all electrons of the atoms travel.
What is produced when two atoms combined?
Molecules are formed when two or more atoms combine to form a new unit of matter. The properties of the resulting molecule are always vastly different from the combining atoms. For example, water is formed when hydrogen and oxygen (two highly reactive gases) combine.
Which formula represents covalent compounds?
In the chemical formula for a covalent compound, the numbers of the different atoms in a molecule are represented by subscripts. For example, the formula for the compound named carbon dioxide is CO2. Q: What is the chemical formula for dinitrogen trioxide? A: The chemical formula is N2O3.
How do ionic bonds affect the properties of ionic compounds?
How do ionic bonds affect the properties of ionic compounds? The bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a poor conductor. One compound is covalent, and the other is ionic.
Which characteristic best explains the difference in melting behavior of covalent substance is an ionic substances?
Which characteristic best explains the difference in melting behavior of covalent substances and ionic substances? Ionic substances have weaker intermolecular attractions. Ionic substances usually have stronger atomic bonds.
How does a periodic table help in predicting the formula of a stable ionic compound?
How does the periodic table help in predicting the formula of a stable ionic compound? Metals in Group 1 form cations with a -1 charge. Metals in Group 1 form anions with a +1 charge. Metals in Group 2 form anions with a -2 charge.
What determines strength of covalent bond?
The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. Multiple bonds are stronger than single bonds between the same atoms.
What determines bond energy?
Bond energy is determined by measuring the heat required to break one mole of molecules into their individual atoms, and it represents the average energy associated with breaking the individual bonds of a molecule. Breaking the O-H bond in the hydroxide ion requires an additional 424 kJ/mol.
