Answer:
Solid, liquid or gas. So there is movement no matter the state. The key variable is density. The higher the density the less movement. In solids the motion can be so small it's very hard to measure. Gas on the other hand is easy the motion being large. Bear in mind temperature plays a big role. Higher temps bring faster motion. Finally the pressure of the gas brings about less motion the higher it is as the molecules are closer together & can't move as much.
Explanation:
Answer:
Electronegativity = 1.87.
Ionic radius = 109 pm.
Atomic radius = -39 pm
First ionization energy = 410 kJ/mol
Explanation:
Hello!
In this case, since electronegativity, ionic radius, atomic radius and first ionization energy are periodic properties that have specific trends, we can summarize it by realizing that oxygen and beryllium belong the same period 2 and differ in group, 6A and 2A respectively.
In such a way, the required comparison is written below:
Electronegativity = 3.44 (oxygen) - 1.57 (beryllium) = 1.87.
Ionic radius = 140 pm (oxygen)- 31 pm (beryllium) = 109.
Atomic radius = 73 pm (oxygen) - 112 pm (beryllium) = -39 pm
First ionization energy = 1310 kJ/mol (oxygen) - 900 kJ/mol (beryllium) = 410 kJ/mol
It means that electronegativity, ionic radius and first ionization energy increases from left to right whereas the atomic radius from right to left.

0,26mol ------- 13g
1mol ------- x
x = (13g*1mol) / 0,26mol = 50g
