Question
Use the periodic table to answer the question.

An illustration shows the periodic table of elements. The elements in the periodic table are arranged in groups (columns numbered 1 through 18) and periods (rows numbered 1 through 7) such that the atomic number increases along a period from left to right. The elements are divided into the following categories: · Alkali metals · Alkaline earth metals · Transition metals · Post-transition metals · Lanthanides · Actinides · Metalloids · Nonmetals · Noble gases · Unknown The elements are also classified on the basis of their physical states as follows: · Solid · Liquid · Gas · Unknown The element sulfur is enlarged with the following properties. · Chemical symbol: S · Name: Sulfur · Atomic Number: 16 · Atomic mass: 32.06 · Common oxidation states: 6, 4, 2, negative 2 · Electronegativity: 2.58 · Ionization energies: 999.589 · Electron configuration: [Ne] 3s2 3p4

Answer 1

In the scenario you described, the two atoms share six electrons, which indicates they are forming a triple bond. This type of bonding occurs between certain nonmetal atoms.

Looking at the options provided:

• N2 (Nitrogen): Nitrogen forms a triple bond with another nitrogen atom, sharing three pairs (6 electrons).
• Si2 (Silicon): Typically, silicon forms single bonds.
• F2 (Fluorine): Fluorine forms a single bond, sharing only two electrons.
• O2 (Oxygen): Oxygen forms a double bond, sharing four electrons.

Given that the question specifies that the atoms share six electrons, the correct response is:

N2 (Nitrogen).
