Question

A) -6
B) -2
C) +1
D) +6
E) -1
F) +2

12. How many sulfur atoms do you need for this reaction to produce 1 molecule of CS2 and 2 molecules of H2S?
A) 1
B) 2
C) 3
D) 4

13. Looking at the periodic table, determine the number of valence electrons present in Phosphorous (P).
A) 5 valence electrons
B) 2 valence electrons
C) 3 valence electrons
D) 4 valence electrons

Answer 1

11. The charge of Sodium (Na) when it bonds with other atoms is C) +1. Sodium is an alkali metal in Group 1 of the periodic table and typically loses one electron to achieve a stable electron configuration.

12. To produce 1 molecule of CS2 (carbon disulfide) and 2 molecules of H2S (hydrogen sulfide), you need a total of 4 sulfur atoms. Therefore, the answer is D) 4.

13. The number of valence electrons present in Phosphorous (P) is A) 5 valence electrons. Phosphorus is in Group 15 of the periodic table, which means it has five valence electrons.
