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 else can I help you with?
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
How does atomic radius increase or decrease horizontally or vertically across the periodic table?
Across a period (horizontal), atomic radius decreases due to increasing nuclear charge pulling electrons closer. Down a group (vertical), atomic radius increases due to the addition of new energy levels further from the nucleus.
When you read the periodic table horizontally what happens to the atomic number?
It is increasing consecutively.
What is the trend for atomic radius horizontally and vertically on the periodic table?
Horizontally: decreasing from left to right.Vertically: increasing from top to bottom.
What is the general trend in densities for period 2?
The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.
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.
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
Why does atomic size tend to decrease with increasing atomic number across a row of the periodic table?
electronegativity
What patterns do you notice as you move down the groups on the Periodic Table?
As you move down the groups on the Periodic Table, you generally observe an increase in the number of electron shells, leading to an increase in atomic size. Additionally, there is a trend of increasing reactivity in alkali metals and decreasing reactivity in noble gases as you move down a group. The ionization energy often decreases as you move down a group due to the increase in atomic size and shielding effect.
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.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
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.
