Question

1pt if you move diagonally across the periodic table from the top right to the bottom left, the number of ________ always increases.
a. electrons
b. neutrons
c. protons
d. isotopes

Explanation:

Moving diagonally from the top right to bottom left of the periodic table means moving to elements with higher atomic numbers. The atomic number of an element equals the number of protons in its nucleus, and this value increases consistently in this direction. Electrons can vary in ions, neutrons vary between isotopes of the same element, and isotopes refer to variants of elements, not a countable quantity that increases in this pattern.

Answer:

C. protons
