Rank the following in terms of increasing electronegativity. 1. Na, N, O, Mg, F 2. Na, Mg, N, O, F 3. F, O, N, Na, Mg 4. F, O, N
Firlakuza [10]
Answer:
2. Na, Mg, N, O, F (Option 2)
Explanation:
Let's look the electronegativity in the periodic table for each element.
F → 4
Na → 0.9
Mg → 1.2
O → 3.4
N → 3
So the correct orden is Na, Mg, N, O, F
Electronegativity is the ability for the atoms to catch electrons in a bond.
It is a periodic table which increase in a diagonal way, from Fr and Ra, the less electronegatives to F, the most.
Answer:
The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny. ... Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have electrical charges that are equal and opposite.

Answer:
A manipulated variable is also called an independent variable. A responding variable is a variable that the researcher predicts will change if the manipulated variable changes. A responding variable is also called a dependent variable.
