Which of the following statements about non-metals is correct? A. Non-metals tend to have high ionization energy and low electronegativity.
B. Non-metals tend to have low ionization energy and high electronegativity.
C. Non-metals tend to have low ionization energy and low electronegativity.
D. Non-metals tend to have high ionization energy and high electronegativity.

D. Non-metals tend to have high ionization energy and high electronegativity.​

Explanation:

non-metals have to gain electrons, so they have more valence electrons than metals. Therefore, it requires more energy to remove them. ... When a metal loses an electron, a nonmetal gains an electron. So, non-metals have high ionization energy.

Nonmetals have more valence electrons and increase their stability by gaining electrons to become anions. The electronegativities of nonmetals are generally high.
