Question

What would the symbol be for a particle that has 11 protons, 12 neutrons, and 10 electrons?

Answer 1

`""_11^23Na^(+1)` the symbol for sodium

Explanation:

Sodium has an atomic number of 11. The number of protons determines the atomic number. The 11 protons makes an atomic number of 11.

The 11 protons have a charge of +11 while the 10 electrons have a charge of -10. This results in a net charge of +1

`+11 + -10 = +1`

Sodium `""_11^23Na` is the most common isotope of sodium.
The mass of an atom is the sum of the number of protons and neutrons. 11 protons and 12 neutrons results in a total mass of 23

`11 + 12 = 23`

To be totally correct the symbol could be written as `""_11^23Na^(+1)`
