Question

question 9 (4 points) draw the bohr model for neon on your own paper and then fill in the blanks using your periodic table and bohr model. element name: ____ atomic #: __ atomic mass (rounded): __ # of protons: __ # of neutrons: __ #of electrons: __ # of energy levels (shells): __ # of valence electrons: ____ blank 1: blank 2: blank 3: blank 4: blank 5: blank 6: blank 7: blank 8: submit saved at 4:5

Explanation:

Step1: Element name

Neon is the element, so the element name is Neon.

Step2: Atomic #

Atomic number of Neon is 10 (from periodic table).

Step3: Atomic mass (rounded)

Atomic mass of Neon is approximately 20 (rounded from ~20.18).

Step4: # of protons

Protons = atomic number, so 10.

Step5: # of neutrons

Neutrons = atomic mass - atomic number = 20 - 10 = 10.

Step6: # of electrons

Electrons = protons (neutral atom), so 10.

Step7: # of energy levels (shells)

Neon has 2 energy levels (1st: 2, 2nd: 8).

Step8: # of valence electrons

Valence electrons are in outer shell, 2nd shell has 8, so 8.

Answer:

Blank 1: Neon
Blank 2: 10
Blank 3: 20
Blank 4: 10
Blank 5: 10
Blank 6: 10
Blank 7: 2
Blank 8: 8
