When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
Does atomic size increase from left to right across the periodic table?
it decreases
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 electronegative change going down and across the table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.

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.
Does atomic size increase from left to right across the periodic table?
it decreases
What happen if you move left to right a across a periodic table in metals?
Across a period the metallic character decreases
Does electropositivity increases or decreases as you move left to right across a period on the periodic table?
Electropositivity decreases along a period. The metallic character also decreases.
What is an example of periodicity?
A good example of periodicity would be the size of an atom which decreases across the Periodic Table but increases down the column
What has the smallest atomic radius Na Mg Cl Al?
chlorine. across a period the size decreases

What happens to the melting temperature as you go from left to right across a row in the periodic table?
it increases then decreases
What is the periodic trend for elctronegativity?
Going down a group...electronegativity decreases Going across...electronegativity increases
