The answer to the questions relating to the periodic table is;

Choice BChoice CChoice CChoice DChoice D

Question 1:

For the electron configuration 3p^2, which of the following describes the number of electrons in the given orbital?

The number of electrons in the given orbital, 3p² is; 2 electrons.

Question 2:

Why are the noble gases nonreactive?

The noble gases are nonreactive as a result of their completely filled Valence orbitals. Consequently, no electrons are available for bonding.

Question 3:

Which of the following elements is considered reactive according to the octet rule?

The element which is considered reactive according to the octet rule is Chlorine, Cl. The element, Cl has 7 Valence electrons and as such is highly electronegative and reactive.

Question 4:

Which of the following elements has only one electron in its outermost s orbital?

The element which has only one electron in its outermost s orbital is Sodium, Na. The element sodium is in group I of the periodic table and has one Valence electron located in its outermost s orbital.

Question 5:

Which of the following four orbitals is furthest from the nucleus?

The orbital which is furthest from the nucleus is the 3p orbital.
