it is because in order to gain noble gas configuration same as neon it need to lose one electron so when it loses that electron it became electropositive ion having +1 charge on it.

second reason for having +1 charge is that when sodium loses an electron it will have 10 electron in total and no of protons are 11 so the total charge on ion became positve

When an element has a + or - next to it,

this refers to the element in it's ionic or charged form.

Each element has a set number of protons neutrons and electrons, but most elements ,like sodium -are not in their most stable form unless they complete their electron valence shells-

This can occur by either giving up electrons or grabbing onto electrons.

Sodium has 11 electrons

2 in its its first orbital (1s2)

6 in the second(2p6)

and 1 in the outer orbital (2s1)

But Sodium is not stable with one lone electron spinning around,

so it will always give it up whenever possible, hence it will always be one electron short- giving the element a positive charge.

Sodium forms a 1+ ion because it has only one electron in its outer shell, and a full shell of 8 electrons below it.

Sodium easily loses its one outer shell electron so that it has an outer shell of 8 electrons, which is stable, whereas having only one valence electron is unstable.

Sodium is in group 1, meaning it has only one valence electron. In compounds (ionic) it has given off this electron to a nonmetal element (oxygen, chlorine), so it becomes charged +1.

Na --> Na+ + e-

Sodium (Na) easily loses an electron because it has 1 electron in the outermost shell. By losing this 1 electron, it attains a configuration the same as neon, the stable noble gas. This makes the sodium much more stable. The reason it has a plus 1 charge is because electrons have a negative charge, so losing one makes the ion positive.

they have one more proton than electron. Protons have a positive charge and electrons have a negative charge.

because it has one electron it can share with a non-metal to make a covalent bond.

because for you to ionize the second electron you'l need a large amount of energy that isn't available in nature but can be done in the lab.
