Answer:
Both the atomic mass and the atomic number increase from left to right
Explanation:
On the periodic table, both atomic mass and atomic number increase from left to right.
The periodic table is a grouping of elements based on their atomic number. Atomic number is the number of protons in an atom. These are the positively charged particles.
- From left to right, the number of protons increase and hence the atomic number.
The atomic mass is made up of the number of protons and neutrons.
Since the number of protons increase left to right, the atomic mass will also increase.
So, atomic mass and the atomic number increase from left to right.
