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.

Ithink d hope that

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
