Question

nitrogen boron 5 3 identify the element and number of valance electrons in each atom below: what are valence electrons? • electrons found in the outermost energy level. • maximum number of valence electrons is eight (8). identify the element and number of valence electrons in each atom below: element name:? valence electrons:? element name:? valence electrons:?

Explanation:

Step1: Recall electron - shell rules

The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8 electrons. Valence electrons are in the outermost shell.

Step2: Analyze first atom

If the first atom has 2 electrons in the first shell and 5 electrons in the second shell, the element is nitrogen (atomic number 7). The number of valence electrons is 5.

Step3: Analyze second atom

If the second atom has 2 electrons in the first shell and 3 electrons in the second shell, the element is boron (atomic number 5). The number of valence electrons is 3.

Answer:

First atom: Element Name: Nitrogen, Valence Electrons: 5
Second atom: Element Name: Boron, Valence Electrons: 3
