Question

Explain carbides of first transition series

Answer 1

In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides.

Answer 2

Answer:

A compound made of carbon and metal is typically referred to as carbide in chemistry. Carburizing, also known as carbide, is the technique used in metallurgy to create carbide coatings on metal objects.

Explanation:

Carbides are given at a high temperature of 2000–2200 °C on warming progress metals or metal oxides with carbon.

There are two types of carbides formed by the first transition series components.

a. Ionic carbides or electrovalent carbides are additional names for these carbides, which resemble salt. This type of carbide is composed of metals like Sc, Cu, Zn, and others.

b. Metallic carbides, also known as interstitial carbides, are these carbides. Such carbides are formed by metals like Ti, V, Mn, Fe, and Co. When carbon and metal are heated, these types of carbides are produced.

The electronic configurations of transition metals like ns and (n-1)d electrons that have surfaced while writing the electron configuration of a first transition series atom.

• In the particles from Hf to Hg, the 14 electrons have not been typed in.
• Mo (molybdenum) has an electron configuration similar to Cr's, thus both elements are green.
• All of the metals—aside from palladium, which has just one ns electron—appeared in blue. Pd does not.
• Ten electrons are located in the (n-1)d orbitals in Cu, Ag, Au, and Pd. With the exception of copper, these metals are often very soft, rare, really inert, and utilized in ornaments.

Hence, the carbides of the first transition series are explained above.
