If you traveled to mars, what would be true? a. you would have the same mass, but you would weigh more b. you would have less mass, and you would weigh less c. you would have the same mass, but you would weigh less d. you would have less mass, and you would weigh more

C.

Explanation: Your mass can't change due to the law of energy conservation, but your weight would be less because of the lack of gravity on mars

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

i think its 100.

hope this !
