### How do you work out how to times a positive number by a negative number?

A positive number times a positive number will always get you a
positive number
A negative number times a negative number will always get you a
positive number
(same signs will get you a positive number)
but
A positive number times a negative number will always get you a
negative number
or
A negative number times a positive number will always get you a
negative number
(different signs will get you a negative number)

###### Asked in Atoms and Atomic Structure, Particle Physics

### How do you get the number of neutrons in a element?

You can get the number of neutrons of an element by taking the
number of protons, the number of electrons, or the atomic number of
the element (seeing as they are all the same number) and subtract
that number from the atomic mass. This will give you the number of
neutrons of an element.
EXAMPLE: THE ELEMENT -BERYLLIUM (Be)
Atomic number/Proton number/Electron number =4
Mass number= 9
To find neutron number: Mass number- Atomic number/Proton
number/Electron number
That is : 9-4=5
And the number 5 would be your answer for the NEUTRON
NUMBER.
