Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
decreases
The atomic number increases
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.
As you move from left to right in the periodic table, the number of protons in the nucleus of an atom increases by one in each element. This increase in the number of protons defines the atomic number and determines the element's position in the periodic table.
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.
No. It goes from metals on the left and middle, to metalloids towards the right, and on the very right, non metals.
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 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 size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.
Towards the bottom, atomic mass increases. Atomic number also increases.
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
