The elements combine with other elements in order to complete their octet and attain stability. The combination can take place either by transfer of electrons or by sharing of electrons. The sharing of electrons results in formation of covalent bond whereas transfer of electrons results in the formation of ionic bonds. The loss of electrons will result in the formation of cation whereas the gain of electrons results in formation of anion. The two oppositely charged ions are held together by electrostatic force of attraction between them.
Hence, an ionic is a force that holds two oppositely charged ions together.
Answer:
chemical energy
Explanation:
cordless power saw has rechargeable battery attached to it.
and we know storage energy in battery is chemical hence cordless power saw has chemical energy present in it.
When the saw is operated, the chemical energy is converted into electrical energy which causes the motor fitted in power saw to move.
Thus,
in cordless power saw
chemical energy is converted into electrical energy
electrical energy is converted into mechanical energy.
