What elemental trend exists in each row as we move from left to right on the periodic table?

Number of protons decreases
Number of protons increases
Chemical reactivity of metals increases
Chemical reactivity of nonmetals decreases

Respuesta :

i believe the number of protons increases. Since as one moves left to right the radius of each element increases and also becomes less metallic.

The correct answer to your question is the second option.

The element trend that exists in each row when we move from left to right in the periodic table is going to be that the number of protons increases.

If you were to look at the periodic table and move from left to right in each row, you would notice that the atomic number of each element gets larger by 1 (keep in mind that the atomic number of an element is the same as the amount of protons that an element has, for example: Gold’s atomic number is 79, so it has 79 protons.)

I hope this helps you! :)
