What nuclear particle determines the isotope of an atom?

The answer in my opinion would be Electrons, because neutrons don't have a charge, and the amount of protons is set in every element, the only nuclear particles that has a charge and can vary, are electrons.

Hope this helps!

3. Determine the moles of sodium, Na, containing 7.9x1024 atoms.

-BARSIC- [3]

Answer:

12.7mol Na.

Explanation:

Hello there!

In this case, according to the concept of mole, which stands for the amount of substance, we can recall the concept of Avogadro's number whereby we understand that one mole of any substance contains 6.022x10²³ particles, for the given atoms of sodium, we can calculate the moles as shown below:

$7.9x10^{23}atoms*\frac{1mol}{6.022x10^{23}atoms} \\\\$
