A sodium ion is noted as Na+ because it has an overall charge of __________.ANSWERIt cannot be determined as written.+1+2-1

If Sodium has 10 electrons and a mass number of 23, it would be classified as an  and would have electrical charge equal to (enter a numerical answer with a charge sign in front of the number if necessary).

State the difference between sodium atom and sodium ion.

(a) Give the formulae of the ions present in sodium phosphate.

Sodium (Na) has an atomic number of 11.  Its electron configuration (by shells) is therefore:A  2, 8, 1B  1, 2, 8C  2, 2, 7D  2, 7, 2*1 pointABCD

How many chloride ions are present arounda sodium ion in the sodium chloride crystal ?
