question 2 (2 points)
on a scrap sheet of paper, draw the bohr model for calcium (ca). use your model to fill in the following information on the number of electrons
__________ electrons in energy level #1
__________ electrons in energy level #2
__________ electrons in energy level #3
__________ electrons in energy level #4
__________ valence electrons

Explanation:

Step1: Recall electron - filling rules

The first energy level (n = 1) can hold a maximum of 2 electrons.

Step2: Fill second energy level

The second energy level (n = 2) can hold a maximum of 8 electrons.

Step3: Fill third energy level

The third energy level (n = 3) can hold a maximum of 8 electrons before starting to fill the fourth level for calcium.

Step4: Determine remaining electrons

Calcium has an atomic number of 20. After filling the first three levels (2 + 8+8 = 18 electrons), there are 2 electrons left for the fourth energy level.

Step5: Identify valence electrons

Valence electrons are the electrons in the out - most energy level. For calcium, the out - most level is the fourth energy level with 2 electrons.

Answer:

Blank 1: 2
Blank 2: 8
Blank 3: 8
Blank 4: 2
Blank 5: 2
