The elements that form compounds difficulty in the fourth period in the periodic table
- In the fourth periodic table, there contain 18 elements that forms compounds difficulty beginning with potassium and ending with krypton – one element for each of the eighteen groups.
- This is as a result of the additional 10 electrons that are contributed by the the sublevel.
The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).

Answer:
Ionization energy is the energy required to remove an electron from a specific atom. It is measured in kJ/mol, which is an energy unit, much like calories. The ionization energies associated with some elements are described in the Table 1. For any given atom, the outermost valence electrons will have lower ionization energies than the inner-shell kernel electrons. As more electrons are added to a nucleus, the outer electrons become shielded from the nucleus by the inner shell electrons. This is called electron shielding .
Explanation:
a little summary
Ionization energy refers to the amount of energy needed to remove an electron from an atom.
Ionization energy decreases as we go down a group.
Ionization energy increases from left to right across the periodic table.
Answer:
An expansion of suitable living space
Explanation:
Increase occurs in the population of the organism only occurs when there is a suitable environment present for that organism. Suitable environment means that place where all the needs of the organism are available such as food, water and shelter etc. If food and water are present in large amount and decrease in animals occurs that prey on that organism will increase the population of the organism.
Answer: ![\frac{V_1}{V_2}=\frac{n_1}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7Bn_1%7D%7Bn_2%7D)
Explanation:
According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,
![V\propto n](https://tex.z-dn.net/?f=V%5Cpropto%20n)
or,
![\frac{V_1}{V_2}=\frac{n_1}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7Bn_1%7D%7Bn_2%7D)
where,
= initial volume of gas
= final volume of gas
= initial moles of gas
= final moles of gas
