Describe the periodic trend in the ionization energy of elements down a group. Use the periodic table, ionization energy and your knowledge of atomic radius as evidence.

As we move down the group it increases.

Explanation:

This is because the electrons are farther away from the nucleus and hence they are not tightly bounded.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
