What direction are the arrows pointing on the periodic table for atomic radius?
Draw three arrows to the left of the periodic table. These arrows should show the trends (from top to bottom) for atomic radius, electronegativity, and ionization energy.
How the pattern in ionization energy across a period of the periodic table compares to the pattern in atomic radius across a period?
In general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
What pattern do you see as you move from left to right across a period on the periodic table?
electronegativity
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.
What is the pattern of ionization energy in the periodic table?
Ionization energy refers to the amount of energy needed to remove an electron from an atom. Ionization energy decreases as we go down a group. Ionization energy increases from left to right across the periodic table.
What is the best explanation for the patterns found in the periodic table for ionization energy and atomic radius?
The smaller the atomic radius, the more closely the electrons are held by the nucleus, and thus the higher the ionization energy. So, in general, ionization energy increases from the bottom-left to the upper-right of the periodic table.
What are the 4 trends of the periodic table?
Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character.
What patterns do you see in the periodic table as you move down columns?
DECREASES TOP TO BOTTOM across the periodic table.
- As you move left to right, the atomic radius gets SMALLER, so atoms hold on to their electrons more tightly and are more reactive.
- As you move down a group, the atomic radius gets LARGER, so atoms have a weaker hold on their electrons and are less reactive.
What elemental trend exists in each row as we move from left to right on the periodic table?
Ionization Energy increases from left to right on the periodic table. Atomic radius decreases moving left to right on the periodic table.
