If you have 30 atoms of potassium how many atoms of f would need to go with it for all of the atoms of potassium to compound.

Both Potassium and Fluorine only form one bond. Each potassium atom will donate there electron to 1 fluorine atom to form a bond. Therefore, you will need 30 Fluorine atoms.

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
