Answer:Sulfur is to the immediate right of phosphorus in the same row in the periodic table. Which of the following statements compares the radius and number of protons of nitrogen and oxygen atoms? Sulfur has a smaller radius and one more proton than phosphorous.
Answer:
Sulfur has a smaller radius and one proton more than phosphorous.
Oxygen has a smaller atomic radius than Nitrogen and one more proton than Nitrogen.
Explanation:
In the periodic table, there are various trends followed by the elements.
Atomic Radius: The atomic radius of elements decreases across the period from left to right. This is because the number of shells in a period remain same while the number of neutrons and protons in the nucleus (nucleons) keep increasing. This results in a greater force of attraction between opposite charges, and therefore atomic radius decreases across a period from left to right.
Atomic number: The atomic number is equal to the number of protons in an atom of an element. It increases across a period from left to right.
Hope this answer helps you.
