Hello!
On the periodic table, as we go down the periodic table, the ionization energy decreases, but as we go across the periodic table (left to right), the ionization increases.
On the periodic table, lithium (Li) is located in column one, beryllium (Be) is located in column two, and (B) boron is located in column 13. As stated above, when we go across the periodic table (left to right), the ionization increases.
Therefore, the element with the highest ionization energy is Boron, or symbol B on the period table.
Answer:
B) P₂O₅
Explanation:
A) MgCl₂
Molar mass of Mg = 24
Molar mass of Cl = 35.5
Molar mass = 24 + 2×35.5 = 95 g/mol
B) P₂O₅
Molar mass of P = 31
Molar mass of O = 16
Molar mass = 31 ×2 + 5×16 = 142 g/mol
C) BaCl₂
Molar mass of Ba = 137.33
Molar mass of Cl = 35.5
Molar mass = 137.33 + 2×35.5 = 208.33 g/mol
D) AlCl₃
Molar mass of Al = 27
Molar mass of Cl = 35.5
Molar mass = 27 + 3×35.5 = 133.5
