Question

In the atom of Chlorine, how many electron orbitals are there?

Answer 1

number of electrons will equal the number of protons

Answer 2

if you have Cl- it has number of protons plus one electron

but just Cl it is electrons = protons

Answer 3

the number it is on the periodic table corresponds to the number of protons it has

Answer 4

So it has 17 protons?

Answer 5

yup

Answer 6

Also,

molecular mass - protons = average number of neutrons in an element of that type.

Answer 7

for instance if you are given chlorine 35 or 35g/mol

35-17 = 18 neutrons

Answer 8

the molecular weight of elements on the periodic table aren't exact numbers because they are the average molecular weight of multiple isotopes based on their abundance in nature.

Answer 9

Isotopes just differ by number of neutrons. Number of protons dictates the identity of an element

Answer 10

so there is carbon 12 which has 6 neutrons, and carbon 13 which has 7 neutrons etc

Answer 11

hope this is helpful

Answer 12

yes it is, thanks haha.
