Freezing
Explanation:
This change in state when surface of a lake changes to hard ice is known as freezing.
- When a solid is heated, it melts and changes to a liquid. On further heating, it changes to vapor and the randomness increases.
- When a liquid is cooled below its freezing point, it changes to a solid such as ice for water.
- The phase change is known as freezing.

Answer:
The correct answer is option 1 "F(2-) "less than" C2(2+) "less than" O(2-) "less than" N(2-)".
Explanation:
Bond order is a term used in chemistry to identify the number of electrons involved in making the bonding between two or more atoms in a molecule. Bond order is equal to half the difference between the number of bonds in the atoms minus the number of antibonds. Therefore, the correct order of bond order from smallest to largest is as follows:
1. F(2-): equals to 0.5 (it has 8 bonds and 7 antibonds)
2. C2(2+): equals to 1 (it has 4 bonds and 2 antibonds)
3. O(2-): equals to 2 (it has 8 bonds and 4 antibonds)
4. N(2-): equals to 2.5 (it has 8 bonds and 3 antibonds)
A metal that would be magnetic is nickel
