The answer is - D. are constantly in motion
These plates move back and forth and sometimes even end up going one above other
Answer:
Gallium - Phosphorous - Fluorine - Chlorine
Explanation:
Electrical to chemical energy
Explanation:
If the batteries in a flashlight are rechargeable, the energy conversion that would take place to recharge the battery is from electrical to chemical energy.
- A battery is an electrochemical cell in which chemical reactions produces electrical currents.
- This is a typical energy conversion from chemical to electrical energy.
- When such batteries are to be recharged, the revere process is followed.
- Electrical energy are used to drive chemical reactions.
- This in turn makes the battery recharged and on its own, it can further chemical reactions to produce electrical energy.
- During charging, the potential of the battery increases.

Answer: A) Na+ and O2-
Explanation:
To know the electronic configuration, one has to determine the numbers of electrons present in each atom.
Na+ means a sodium atom that has lost one valence electron. A Sodium atom initially has 11 electrons, but having lost an electron making it 10 electrons remaining with electron configuration of 1s2 2s2 2p6.
O2- means oxygen atom that has gained two valence electrons. An oxygen atom initially has 8 electrons, having gained two electrons makes it 10 electrons with electron configuration of 1s2 2s2 2p6. same as Na+
The purpose of gaining or losing electrons is to attain a stable duplet or octet structure.
