Why do atomic numbers increase from left to right across any given row on the periodic table?
Atomic numbers increase from left to right across a row on the periodic table because each successive element has one more proton in its nucleus than the previous element. This increase in protons corresponds to an increase in the overall positive charge of the nucleus, which also influences the arrangement of electrons surrounding the nucleus. As a result, the atomic number, defined as the number of protons, increases sequentially across the row. This systematic organization reflects the periodic law, where elements exhibit periodic properties based on their atomic structure.
Does atomic size increase from left to right across the periodic table?
it decreases
What increases in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This increase in atomic number corresponds to an increase in the number of protons in the nucleus of the atom.
What goes across the periodic table?
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.
What is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.

How do atomic numbers and atomic masses increase in the periodic table?
Atomic numbers increase from left to right across a period on the periodic table. This is because each element in a period has one more proton in its nucleus compared to the element before it. Atomic masses generally increase from left to right as well, but there may be deviations due to isotopes or other factors. Within a group or column, atomic numbers and atomic masses increase from top to bottom as each successive element has more electrons and neutrons than the one above it.
Does atomic size increase from left to right across the periodic table?
it decreases
What increases in the periodic table?

What goes across the periodic table?
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.
How much does the atomic number increase bye as you go across a row on 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.
How much does the number increase by as you go across a row on the periodic table?
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.
What is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.
When you move across the periodic table from left to right what happens to the number of protons contained by each element?
the numbers increase (going right) and decrease (going left)
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
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.
