Question

An atom of fluorine has an atomic number of 9 and an atomic mass of 19. The atom contains
Select one:
a. 19 protons, 19 electrons, and 9 neutrons.
b. 19 protons, 10 electrons, and 9 neutrons.
c. 9 protons, 10 electrons, and 10 neutrons.
d. 9 protons, 9 electrons, and 10 neutrons.

Answer 1

Answer 2

c

Answer 3

u guessing or r u sure

Answer 4

@AllTehMaffs is he correct

Answer 5

There should only be 9 electrons

Answer 6

atomic number gives the number of protons, the mass - atomic number = # of neutrons. charge of fluorine is -1(noble gas) and so it will have 1 more electron than proton therefore 9 + 1 = 10 electrons

Answer 7

halogen*

Answer 8

Neon has 10 electrons; fluorine has 9

Answer 9

i could be wrong, i've already passed chemistry and never have to take it again, so my memory could be wrong

Answer 10

ok so which one are we looking at.

Answer 11

It likes to nom electrons from other atoms to fill its outer shell; that's why it's so caustic.

It's D methinks

Answer 12

*nom is the scientific term

Answer 13

probably D, im thinking of F as in F no charge vs F-

Answer 14

yeah - when it ionizes it's -1

Answer 15

So the answer is D.

Answer 16

yah

Answer 17

okkkaaaay I have like one more

Answer 18
