Given information
The change in energy of a neutral atom in a gaseous phase to form a negative ion when an electron is introduced to the atom is known as electron affinity. Each pair's element with the highest negative electron affinity must be discovered.
Step-by-step explanation
Step 1.
The given group of atoms is, and
The amount of energy released when a neutral atom in the gaseous state acquires an electron from an anion is measured by electron affinity (EA).
Electron affinity (EA) increases from left to right across a period (row) and declines from top to bottom across a group, according to periodic tendencies (column).
The atomic number of is 11 and for is 15.
