1. Atomic size across a period .......... with increase in nuclear charge of the element.

Question

With reference to the elements of the modern periodic table.

Fill in the blanks with the appropriate word/s in each case.

1. Atomic size across a period .......... with increase in nuclear charge of the element. 

2. Ans. With increase in nuclear charge the nuclear attraction for outer electrons ............., hence ionisation potential ...........

3. Increase in nuclear charge of an atom .............. the tendency of the atom to lose electrons. 

4. Elements with stable electronic configuration e.g. neon have an electron affinity value of ......

5. An atom with a small atomic radii takes up electrons ........... readily than an atom with a large radii.

Answer 1

1. Atomic size across a period decreases with increase in nuclear charge of the element. .

2. With increase in nuclear charge the nuclear attraction for outer electrons increases, hence ionisation potential increases.

3. Increase in nuclear charge of an atom decreases the tendency of the atom to lose electrons

4. Elements with stable electronic configuration e.g. neon have an electron affinity value of 0.

5. An atom with a small atomic radii takes up electrons more readily than an atom with a large radii.
