Question

the position of a four element ABCD in the modern periodic table are shown below.What element is most likely to form an acidic oxide​?

Answer 1

A:Li

B:Mg

C:Br

D:Xe

Bromine

Answer 2

Bromine

Explanation:

As per the given place of the elements in the periodic table format the elements are -

A - Li (Lithium)

B - Mg (Magnesium)

C - Br (Bromine)

D - Xe (Xenon)

Bromine is more likely to form acidic oxide.

Bromine is present on RHS of the periodic table and belongs to 17th group and is a non- metal, hence it will form acidic oxide. In case of Lithium and Magnesium the are present on LHS of periodic table and are metals therefore forming basic oxides. On the other hand, Xenon is a noble gas and cannot be oxidized.

The reason for a non-metal to form acidic oxide is they react with oxygen and leads to the production of non -metallic oxides that are usually acidic in nature.
