Which country is called Asia’s diamond?
From ancient times, India was the source of nearly all the world’s known diamonds, and until the discovery of diamonds in South Africa in 1896, India was the only place where diamonds were mined. India has not been a major diamond-producing country since the 1900s, but diamond mining continues.
What is the most metallic element in group 4?
The most metallic element is francium.
What color are raw diamonds?
Diamonds occur in a variety of colors—steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Colored diamonds contain interstitial impurities or structural defects that cause the coloration; pure diamonds are perfectly transparent and colorless.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
Who is diamond of India?
Even though Bal Gangadhar Tilak was his opponent during the funeral of Gokhale in February Bal Gangadhar Tilak praised him as the ‘Diamond of India’, the ‘jewel of Maharashtra ‘and the ‘prince of workers’. The full name of Gokhale was Gopal Krishna Gokhale.
What is Group 11 called?
The Group 11 is composed of copper (Cu), silver (Ag), and gold (Au). Silver and Au belong to the so-called noble metals.
Are raw diamonds worth anything?
With few common inclusions, raw diamonds are more valuable than diamonds with several common flaws. A raw diamond which has a brownish or yellowish tint is stronger but less valuable. On the other side, diamond with less hue is far more valuable. Transparent and colorless diamonds are too rare to find.
Why elements are arranged in 4th period?
The reason for the arrangement of elements in the period is based upon the atomic number. In all periods, including the elements are arranged according to the atomic number in increasing order.
How can you tell a raw diamond?
Put the diamond under the loupe or microscope and look for rounded edges that have tiny indented triangles. Cubic diamonds, on the other hand, will have parallelograms or rotated squares. A real raw diamond should also appear like it has a coat of vaseline over it. Cut diamonds will have sharp edges.
Is Group 4 metal or nonmetal?
Like silicon, germanium is used as a semiconductor, and is widely used in the computer industry. Silicon and germanium are both metalloids, having some characteristics of both metals and nonmetals.Group 4A. (3) (4) (5) (6).
Why does period 4 have 18 elements?
In the modern periodic table, each period starts with the filling of a new principal energy level. Thus, the fourth period begins with the filling of principal quantum number, n=4. Therefore, 9 orbitals, at the maximum, can have 18 electrons and hence, fourth period has 18 elements.
Is group 5 metal or nonmetal?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What is the element in Group 4 Period 4?
titanium Hydrogen Potassium Calcium Scandium Titanium Vanadium.
Does period 4 have 3 valence electrons?
⇒ The fourth shell is left not fully complete, so the remaining 3 electrons are valence electrons in an atom of gallium metal .
Do raw diamonds sparkle?
When a diamond is mined, nature has already determined color, clarity, and most of carat weight. But a rough diamond just looks like a transparent rock. It doesn’t sparkle.
Is diamond stronger than tungsten?
Tungsten metal is rated at about a nine on the Mohs scale of hardness. A diamond, which is the hardest substance on earth and the only thing that can scratch tungsten, is rated at a 10.
Which type of metal is diamond?
Material properties. Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.
Where is diamond found in India?
In India, Andhra Pradesh, Chhattisgarh, and Madhya Pradesh are the three states that produce diamonds. Among them, Madhya Pradesh accounts for about 90% of the total diamond resource of the country.

What is the period 2 halogen?
The elements in period 2 often have the most extreme properties in their respective groups; for example, fluorine is the most reactive halogen, neon is the most inert noble gas, and lithium is the least reactive alkali metal.
What is the last element in period 4?
These are scandium, titanium, vanadium, chromium, manganese, iron, nickel, copper and zinc. At the last of this period there is a noble called krypton. Thus krypton is the last element of the ${4^{th}}$ period.
Is a period 4 halogen?
Bromine (Br) is an element in group 17 (halogen). It does not exist in elemental form in nature. Bromine is barely liquid at room temperature, boiling at about 330 kelvins. Bromine is also quite toxic and corrosive, but bromide ions, which are relatively inert, can be found in halite, or table salt.
