What else can I help you with?
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.
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.
Why do atomic numbers increase from left to right across any given row of the periodic table?
The atomic number increases from left to right across a row of the periodic table because each element in the row has one more proton in its nucleus. This additional proton increases the positive charge of the nucleus, leading to stronger attraction to the electrons in the outer energy levels. This results in the elements in the row having increasing atomic numbers.
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 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.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
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)
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.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
