Question

this is how sodium appears in the periodic table. the arrow is pointing to sodiums number of neutrons. chemical symbol atomic mass combined number of electrons and protons.

Explanation:

In the periodic table, the atomic mass of an element is typically shown below its name. Sodium's atomic mass is \(22.99\). The number of neutrons can be calculated (atomic mass - atomic number), but it's not directly shown as \(22.99\). The chemical symbol is \(Na\). The combined number of electrons and protons (for neutral atoms, electrons = protons = atomic number \(11\), so combined is \(22\), not \(22.99\)).

Answer:

atomic mass
