Question

The atomic numbers of three elements a b and c are 4 8 and 16 respectively. State giving reasons which 2 elements will show similar chemical properties

Answer 1

Given

• Three elements having atomic number 4,8 and 16.

To Find

Pair of element which will exhibit similar chemical properties.

Concepts

• The periodic table is a periodic function of atomic number of elements.

• Periodic table classifies elements into 18 group having similar chemical properties due to similar outer shell electronic configuration.

Solutions

$\boxed{\green{Finding\:electronic\:configuration)}}$

• K shell is filled first .It can have maximum 2 electrons, followed by L shell which can have maximum 8 electrons .N shell can have maximum 18 electrons.

See the attachment

• We observe that element a and b have same configuration in outer shell.They belong to same group and hence, they will have similar chemical properties.

$\boxed{\boxed{\pink{Hence,\:b\:andc\:will\:exhibit\:similar\:chemical\:properties}}}$
