What else can I help you with?
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
What number increases in the periodic table?
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
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)
Does the old periodic table increase by atomic number?
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.
Does atomic density increase or decrease as we go across in a period?
It decreases across a period. Since the atomic number increases, so does no. of protons and electrons. This makes the electrostatic force of attraction between electrons larger and hence the atom shrinks a bit. This makes the radius smaller.
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 number increases in the periodic table?
The atomic number increases in the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and it increases by one as you move from left to right across a period on the periodic table.
What direction does the atomic number increase on 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.
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.
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)
When moving across a period in the periodic table?
The atomic number increases
What stays the same across a period on the periodic table?
the atomic number.
Does the old periodic table increase by atomic number?
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.
Does atomic density increase or decrease as we go across in a period?
It decreases across a period. Since the atomic number increases, so does no. of protons and electrons. This makes the electrostatic force of attraction between electrons larger and hence the atom shrinks a bit. This makes the radius smaller.
What happens as periods increase on the periodic table?
As you move across a period on the periodic table, the number of protons increases, which increases the atomic number. This results in a greater positive charge in the nucleus, leading to an increase in the attraction between the nucleus and the electrons in the outer energy levels. This trend generally results in smaller atomic size and higher electronegativity as you move across a period.
