Answer: The answer to your question is D) Strong nuclear force
Explanation:
In nature, there are four fundamental interactions: electromagnetism, gravitation, weak nuclear force and strong nuclear force.
The Strong nuclear force is responsible for binding protons and neutrons to form a new nucleus.
Weak nuclear force is responsible for radioactive decay which means splitting nucleus.
Answer:
Strontium is smaller
Strontium has the higher ionization energy
Strontium has more valence electrons
Explanation:
It must be understood that both elements belong to the same period i.e the same horizontal band of the periodic table
While Rubidium is an alkali metal(group 1) while Strontium is an alkali earth metal(group 2)
Since they are in the same period, periodic trends would be useful in evaluating their properties
In terms of atomic radius, rubidium is larger meaning it has a bigger atomic size
Generally, across the periodic table, atomic radius is expected to decrease and thus Rubidium which is leftmost is expected to have the higher atomic radius
Since strontium belongs to group 2 of the periodic table, it has 2 valence electrons which is more than the single valence electron that rubidium which is in group 1 has
In terms of ionization energy, the atom with the higher number of valence electrons will have the higher ionization energy which is strontium in this case
Answer:
