Explain the large decrease in atomic radii as you move across a period from group 1 to group 14?

Atomic radius increases down the group due to increase in no.of orbits around the nucleus.

This happens because of the addition of one more shell.

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.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
from left to right the atomic radius decreases as the electrons that get added are added in the same shell as they are in the same period. the shielding effect remains constant but the proton number increases which inturn increases the effective nuclear pull on the electrons bringing the electrons closer to the nuclei hence decreasing the radius of the atom
What happens to the energy needed to remove an electron as the atomic number increases down a family?
The energy needed to remove an electron from an atom generally increases, decrease as you go across a period? Explain why ? please
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
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 BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
How does the atomic radius change from the left to the right horizontal row in the periodic table?

Why does atomic size increase from left to right across a period?
atomic size decreases across a period
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
What happens to the energy needed to remove an electron as the atomic number increases down a family?
The energy needed to remove an electron from an atom generally increases, decrease as you go across a period? Explain why ? please
What is the trend in atomic size across the period from sodium to argon?
across a period, the atomic size decreases as the effective nuclear charge increases.
What does atomic radius do across a period?
It decreases.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
What happens to the atomic number as you move across a period?
.The atomic mass increases
