Question

What is the s,p,d,f configuration of Co?

Answer 1

Hint: The regions of space where electrons are most likely to be found are known as orbitals. A number and a letter are assigned to each orbital. The number represents the electron's energy level in the orbital. As a result, 1 denotes the energy level nearest to the nucleus, 2 the next energy level outward, and so on.

Complete answer:
The regions of space where electrons are most likely to be found are known as orbitals. A number and a letter are assigned to each orbital. The number represents the electron's energy level in the orbital. As a result, 1 denotes the energy level nearest to the nucleus, 2 the next energy level outward, and so on.
The letter refers to the orbital shape. The letters are arranged in the following order: s, p, d, f, g, h,i j, and so on. The letters s, p, d, and f were assigned for historical purposes that we don't need to worry about.
The chemical element cobalt has the symbol Co and the atomic number 27. Cobalt, like nickel, is only present in chemically mixed form in the Earth's crust, with the exception of small deposits found in natural meteoric iron alloys. Reductive smelting produces a hard, lustrous silver-gray metal as the free ingredient.
Cobalt's s,p,d,f configuration is determined by the element's location on the periodic table.
Atomic Number of Cobalt = 27
Spdf configuration: \[1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}4{s^2}3{d^7}\]
