Periodic Trends

A periodic trend is.....

• a pattern change in metallic properties across the periodic table.

• a pattern change in atomic radius across the periodic table.

• a pattern change in ionization energy across the periodic table.

• a pattern change in electronegativity across the periodic table.

• all of the above

What is the best answer for atomic radius?

• How big an atom is on the periodic table

• The distance from the nucleus to the atom's outside valence electron

• A trend that is the same as ionization energy.

• The distance from one valence electron to another

What is the trend for atomic radius on the periodic table? You may google a picture to aid you.

• It increases from bottom to top and from left to right

• Increases from right to left and from top to bottom

• It increases top to bottom and from left to right

• None of the above

What is the trend for ionization energy on the periodic table? You may google a picture to aid you.

• It increases from bottom to top and from left to right

• Increases from right to left and from top to bottom

• It increases top to bottom and from left to right

• None of the above

What is the trend for electronegativity on the periodic table? You may google a picture to aid you.

• It increases from center to top and from left to center

• Increases from right to left and from top to bottom

• It increases top to bottom and from left to right

• It increases from bottom to top and from left to right

What is ionization energy?

• Energy required to remove a proton from the nucleus

• Energy required to remove a neutron from the nucleus

• Energy required to remove a valence electron from another atom

• How attracted an atom is for another's electron

What is electronegativity?

• Energy required to remove a valence electron from the nucleus

• The unattraction between two like charges

• The attraction between two like charges

• How attracted an atom is for another's electron.

According to Coulomb's law, why does the atomic radius decrease from left to right across the periodic table

• Energy rings are being taken away.

• All the atoms receive unlike charges which smashes the atoms together

• There is an increases in protons in the nucleus and electrons in the outside rings increasing a force of attraction that pulls the particles closer to each other.

• There is an increases in neutrons in the nucleus and electrons in the outside rings increasing a force of attraction that pulls the particles closer to each other.

Why does the atomic radius increase in size going down a group?

• More protons and neutrons are added to the nucleus

• Rings are being added creating a shielding effect blocking attraction

• Only more protons are added to the nucleus

• None of the above
