Question

As nuclear charge increases, atomic orbitals become smaller and more stable.

• A. True
• B. False

Answer 1

The correct option is A True

As the atomic number increases the effect of nuclear charge on the outer most shell increases mainly in a period not in a group hence it make orbitals small and in a period as we from left to right at the end we get a stable compound that is a noble gas. From this, we could come to a conclusion that stability increases as atomic number increases. The main reason is that of more number of unpaired electrons. Hence given statement is true.
