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 happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
How does atomic number vary across the periodic table?
It goes up by one left to right.
What happens to the atomic size from the top to the bottom of the periodic table?
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.
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.
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.
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 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 stays the same across a period on the periodic table?
the atomic number.
When moving across a period in the periodic table?
The atomic number increases
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
Why does atomic size tend to decrease with increasing atomic number across a row of the periodic table?
electronegativity
When looking across a period of the periodic table from left to right when happens to the atomic number and 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.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
When you read the periodic table horizontally what happens to the atomic number?
It is increasing consecutively.
