#""_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)#
