Question

use the periodic table to answer the question. a reaction occurs that results in a molecule with two atoms of the same element. the atoms share six electrons. which molecule could be the product of the reaction? (1 point) f₂ n₂ o₂ si₂

Explanation:

Step1: Analyze valence - electron needs

In a covalent bond where atoms share electrons, we need to find an element whose atoms can form a bond sharing six electrons.

Step2: Check valence electrons of each option

• Fluorine ($F$) has 7 valence electrons. In $F_2$, the two $F$ atoms share 1 pair (2 electrons) to complete their octets.
• Nitrogen ($N$) has 5 valence electrons. In $N_2$, the two $N$ atoms form a triple - bond, sharing 3 pairs (6 electrons) to complete their octets.
• Oxygen ($O$) has 6 valence electrons. In $O_2$, the two $O$ atoms form a double - bond, sharing 2 pairs (4 electrons) to complete their octets.
• Silicon ($Si$) has 4 valence electrons. In $Si_2$, the bonding would not result in sharing 6 electrons in a simple di - atomic molecule to complete octets.

Answer:

$N_2$
