Question

A) Why does Si have a larger radius than S?

Si has more protons in its nucleus than S.

Si is further to the left on the periodic table than S.

Si has more mass than S making it larger.

Si has its valence electrons in a higher energy level than S.

The valence electrons in S feel a greater Zeff than those in Si.

Why does K have a smaller first ionization energy than Na?

K has a greater Zeff.

Na holds its valence electron closer to the nucleus.

Na is further up on the periodic table.

K has more protons in its nucleus.

Which of the following atoms has the greatest Zeff?

Si has more protons in its nucleus than S.

Si is further to the left on the periodic table than S.

Si has more mass than S making it larger.

Si has its valence electrons in a higher energy level than S.

The valence electrons in S feel a greater Zeff than those in Si.

A.The valence electrons in S feel a greater Zeff than those in Si.
