8 0

Answer:For Fe

Z=26

Explanation:

1s2 2s2 2p6 3s2 3p6 4s2 3d6

Are there 26 electrons here? Why should there be 26?

So going back to the inert gas, argon ( Z=18 ), we get

[Ar] 4s2 3d6


Make sure to check your work by counting the electrons you have

) Experimental evidence indicates that the nucleus of an atom
geniusboy [140]

Answer:

A (contains most of the mass of the atom)

Evidence has it that a proton is about 2000 times as massive as an electron.

And there is usually multiple protons and neutrons in the nucleus

From what I just said, you can say that B is wrong

C however is also wrong because protons have a +charge and neutrons are neutrle which means you always have a charge > (greater than) 0

And D is wrong because electrons (which are not in the nucleus) have a neg charge. and protons have a + charge and are in the nucleus

So your answer is A

Hope it helped
