Question

Using the trends in the periodic table, rank the following atoms in order of increasing electronegativity. Na, H, Li
Br, Cl, I
B, O,C

Answer 1

Ranking the atoms in order of increasing electronegativity:

For the first set (Na, H, Li):
1. Li (Lithium)
2. Na (Sodium)
3. H (Hydrogen)

For the second set (Br, Cl, I):
1. I (Iodine)
2. Br (Bromine)
3. Cl (Chlorine)

For the third set (B, O, C):
1. C (Carbon)
2. B (Boron)
3. O (Oxygen)

Please note that the order of electronegativity can be subject to slight variations depending on the specific periodic table and factors such as atomic radius and electron configuration.
