How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
Does the atomic radius decrease as you move up a group and across a period from left to right on the periodic table?
the atomic radius decreses from left to right in periodic table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
In general the atomic radius of an atom as you move down a column in the periodic table?
Decreases. Look at the images under atomic radius, on wikipedia.
What patterns do you notice as you move down the groups on the Periodic Table?
As the orientation goes down, the elements become more solid. :-)
Why does the size of d-block elements decrease gradually in the periodic table?
As increase in proton number, the attraction from nucleus towards electrons increased. This will pull the electrons stongly. So, the size/ atomic radius decreased across the d-block.
How do atomic numbers and atomic masses increase in the periodic table?
The atomic number and atomic masses increase as you move from left to right.
Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
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.
What factors contribute to the decrease in ionization energy within a group in the periodic table as the atomic number increases?
as atomic number is increase the size of the atom goes on increasing as more number of electron is added to the outer most orbit so the nuclear force exerted by the nucleus on electron is less so the affinity to loose electorn is more as the atomic number is increase that is the reason ionization energy decrease with increase in atomic number
