Question

what element has 16 neutron 14 electron 30 atomic mass

Answer 1

To identify an element, look for the number of protons.
Atomic mass - # neutrons = #protons
30-16= # protons
# protons = 14
The element is silicon.

Answer 3

but proton has a atomic mass of of 28 so does that make this one and isotope if so what kind of?

Answer 4

pretty sure it is silicon-30 isotopes but does it have the same 3 of valence electron as the original silicon?

Answer 5

?
The number of neutrons varies from isotopes to isotopes, but the number of protons remains the same.

Typically the number of electrons doesn't change.

In this problem, that is the case.
The number of electrons is 14, and the number of protons is also 14.
The number of neutrons is 16. Therefore, this is an isotope of silicon.

And yes, is it silicon-30 and it does have the same number of valence electrons as the original silicon.
