The head of a pin is 1.5 x 103 m in diameter. If 1.136 x 107 atoms of oxygen can fit across the head of a pin, what is the atomic radius of oxygen? O A 7.57 x 10-10 m
O
B. 1.32 x 10-10 m
O
c. 1.70 x 10-4 m
D. 6.6 x 10-11 m

6.4 cm (max) - 25 cm (min)

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

idk what is it? is this a question that you know the answer or u dont
