What happens to the atomic mass when the atomic numbers increase

Atomic masses increase as the atomic numbers increase.

Explanation: Elements are arranged in the periodic table in increasing order of their atomic numbers. A periodic table is a table showing the arrangement of the elements in the increasing order of their atomic numbers. Atomic number of an element is the number of protons in the nucleus of an atom while atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom.

Atomic number of elements increases across the period from left to right and increases down the group and the atomic masses of the elements increase from left to right across the period and down the group as the atomic number increases.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
