Answer to Question #280727 in Inorganic Chemistry for joe

Question

1. explain how the electronegativity of gallium differs from germanium
2. explain how the ionisation energy of gallium differs from germanium
3. explain how the ionisation energy of gallium differs from indium

Answer 1

1. Germanium have higher electronegativity than gallium .

Germanium is in 14 th group but gallium is in 13 th group and both have d orbital .

14 th group is is right side than 13 th group so , electronegativity increases from left to right

.

2. germanium have higher ionisation energy than gallium .

Left to right in the period ionisation energy increases in the period .

3. Gallium have higher ionisation energy than Indium .

Both the elements is in 13th group .

In the group Towards downward Size increases Ionisation decreases.

So, gallium is above of Indium So , gallium have higher ionisation energy than Indium.
