Explain the following:
“The first ionisation energy of carbon atom is greater than that of boron atom whereas, the reverse is true for the second ionisation energy.

Why the first ionisation energy of carbon atom is greater than that of boron atom whereas, the reverse is true for the second ionisation energy.

The first ionisation energy of magnesium is greater than that of sodium, whereas the reverse is true for second ionisation energy. Explain.

Give reason for the following : a. The first ioisation eathalpy of carbon carbon is greater than that foboron, whereas the reverse is true fore the second ionisation enthalpy . b. Solid carbon dioxie is known as dry ice . c. Why does not silicon form an analogue fo graphite ?

The first ionisation energy of first atom is greater than that of second atom, whereas reverse order is true for their second ionisation energy. Which set of elements is in accordance to above statement?

The first ionisation energy is maximum for

The IE_(1) of C atom is greater than that of boron (B) atom, whereas the reverse is true for IE_(2) . Explain?

The first ionisation enthalpy of nitrogen (Z=7) is greater than that of oxygen (Z =8) but the reverse is true for the second ionisation enthalpy. Explain why.

The first ionisation energy of carbon is much higher than that of silicon . Explain.

Why is the ionisation energy of beryllium greater than that of Li and B?
