Sample Questions

Question 1

What determines the atomic number of an element?

Answer: The atomic number is determined by the number of protons in the nucleus of an atom. It uniquely identifies each element on the periodic table.

Question 2

What is the difference between an atom's atomic mass and its atomic number?

Answer: The atomic number is the count of protons only, while the atomic mass is the total count of protons plus neutrons in the nucleus.

Question 3

What are isotopes?

Answer: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, giving them different atomic masses.

Question 4

As you move from left to right across a period on the periodic table, what happens to electronegativity?

Answer: Electronegativity generally increases from left to right across a period because the nuclear charge increases while the atomic radius decreases, pulling electrons more strongly.

Question 5

What characteristic do all elements in the same group (column) of the periodic table share?

Answer: Elements in the same group share the same number of valence electrons, which gives them similar chemical properties and reactivity.
