the atomic mass in the periodic table increases as you go from left to right across a row.....
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
.The atomic mass increases
Down a group, the atomic radius increases as the number of shells or energy levels increases.
It goes up by one left to right.
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
The atomic number increases by one as you go across a row on the periodic table. Each element in the row has one more proton in its nucleus than the previous element, which is reflected in the increase in atomic number. This trend continues across each row of the periodic table.
The atomic number increases from left to right across the periodic table because the number of protons in the nucleus of an atom increases. This results in a higher positive charge, leading to a stronger attraction to electrons and a closer binding of electrons to the nucleus.
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.

the atomic number.
The atomic number increases
The atomic number increases as one go across a period.
electronegativity
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.
.The atomic mass increases
It is increasing consecutively.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
