Electron affinity is a measure of the tendency of a neutral atom to gain electrons and form a negative ion. It can be represented by a general equation:
X + e- → X-
The value of electron affinity decreases on moving down a group. This is because on moving down a group the atomic size increases as a result the added electron feels less pull or attraction towards the nucleus.
In group 14, Carbon 'C' is the first member and therefore will have the highest electron affinity.
Ans : A) Carbon
Answer:
<h2>1. Ionic compound-

</h2><h2>2. Polar molecular compound-

</h2>
Explanation:
Mg is a metal that has 12 atomic numbers and thus its electronic configuration is
. The outer most shell of this element has 2 electrons so it loses 2 electrons and thus form
ions. Br is a nonmetal and has 35 atomic number so its electronic configuration is
. Since its outermost shell has 7 electrons so it can accept one electron and thus forms
. So magnesium ion and bromide ion combine and forms an ionic compound
.
P is also a nonmetal and combine with Br with covalent bond and due to electronegativity differences form polar covalent compound such as
.
