Answer:
Mg
Explanation:
Mg requires more ionization energy to ionize because it has more protons than Na. If an atom, located within the same period, has more protons, the pull on the electrons will be greater. This makes it more difficult to remove these electrons during ionization.
As a general rule, ionization energy decreases as you go down a column and increases as you move to the right on the periodic table. Therefore, the elements with the highest ionization energies are located on the top right of the periodic table. Ionization energies increase across a group due to the quantity of protons increasing. Ionization energies decrease as you go down a column because the outermost electrons are further from the nucleus (where the protons are), making it easier to remove them.
Answer:
To find the identity of the isotope we must first calculate the mass number
Mass number (M) = A + Z
Where
A is the atomic number
Z is the neutron number
A = 47
Z = 60
M = 60 + 47 = 107
From the options above
The answer is option A

No, the properties of a substance are not affected by the amount of a substance.
There are 0.0713 (g) of Calcium Phosphate Ca3(PO4)2 in 2.3*10^-4 moles of Calcium Phosphate.
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions.
Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.
