  1. The elements in the first group (column) of the Periodic Table are called Alkali Metals. The elements in the second group (column) of the Periodic Table are called Alkaline Earth Metals. Groups (columns) 3 through 12 are called 'Transition Elements'. The elements in the second to last column (group) of the Periodic Table are called Halogens.
  2. Cobalt (Co) From Wikipedia, the free encyclopedia Cobalt is a chemical element with symbol Co and atomic number 27. Like nickel, cobalt in the Earth's crust is found only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.
  3. Co stands for “Cobalt” on the periodic table. Cobalt is a chemical element with Co as its symbol. It belongs to group 9, periodic number 4 of the periodic table. Its atomic number is 27. Cobalt is silver-white in color with a bluish tinge.

Co Periodic Table

Electron affinity is the amount of energy change (ΔE) that occurs when an electron is added in the outermost shell of an isolated gaseous atom.

In other words, when the electron is added to a neutral atom, the energy is either released or absorbed. And this amount of energy change (ΔE) is called electron affinity.

This energy change (ΔE)can be positive, negative or zero.

And the sign of Electron Affinity (EEA) is opposite to the sign of energy change (ΔE).

EEA = – (ΔE)

In simple words, if ΔE is positive, then EEA will be negative. And if ΔE is negative, then EEA will be positive.

What Is A Periodic Table

Points to remember:

  • For exothermic reaction (i.e when energy is released), the change in energy (ΔE) is negative. Hence the sign of Electron Affinity (EEA) will be positive.
  • For endothermic reaction (i.e when energy is absorbed), the change in energy (ΔE) is positive. Hence the sign of Electron Affinity (EEA) will be negative.
  • For neutral process (i.e when energy is neither absorbed nor released), the value of Electron Affinity (EEA) will be zero.

More the positive values of Electron Affinity (EEA), more is the energy released.

Halogens on the periodic table shows more positive values of Electron Affinity (EEA). Hence they indicate that more energy is released when an electron is added to the neutral atom.
