Electricity is a flow of energy. An atom is made of ​ (a)   and electrons. Protons are positively charge and electrons have a negative charge. There's many different atom from the periodic table with different numbers of protons a electrons. One thing they have in common is an equal amount of both. The protons doesn't change. But electrons can increase or decrease and become unbalanced. An unbalance atom is called an ​ (b)   . When electrons increase, the atom has a negative charge and called a negative ion. When electrons decrease, the atom is positively charge and called positive ion. Likes repel and opposites atract. When a (-) ion meet a (+) ion, an electron wil flow from the (-) to the positive. Thats why Electricity is ​ (c)   flows from Atom to ​ (d)   .​
