Question

1. A neutral atom of an element has a nucleus with
nuclear charge 12 times and mass 24 times that
of hydrogen. Calculate the number of electrons,
protons and neutrons in its stable positively
charged ion.​

Answer 1

Answer:

protons is 12

neutrons is 12

electrons is 2,8,8,8

Explanation:

electron had configuration of 2,8,8,6...

they gained 2 electrons...

had a valency of 2-

and stable configuration became 2,8,8,8

Answer 2

Answer:

I can give example for this:;

Explanation:

in in neutral atom of an element has a nucleus with the nuclear charge 13 times and march 27 times of that of hydrogen nucleus. what is the ratio of electrons to protons in stable positively charged ion? solution;!

nuclear charge is 13 times hydrogen atom.

number of protons=13

mass is 27 times hydrogen therefore mass number is=27

10 element is 27 by 13 a l. the stable position iron of Al is Al3+. this in Al3+, there are 13 protons and 10 electrons. hence ratio of electron to proton is 10: 13.

I hope this example is useful for you?!!!
