Chemistry 10/11

Question 1

What happens when you go down a period left to right?

Answer 1

Atom gets larger w/ more protons

Question 2

What happens when to atoms when you go down a group?

Answer 2

Increase in size, more distance between outermost orbital and nucleus

Question 3

Define ionization energy

Answer 3

The minimum energy required to remove the most loosely bound electron.

Question 4

What happens to the ionization energy of atoms as you move from left to right across a period. Explain

Answer 4

Ionization energy increases. The more protons as you go across a period, the more energy it takes to remove an electron from the atom.

Question 5

What happens to the ionization energy of atoms as you move from top to bottom of a group? Explain

Answer 5

Ionization energy decreases. The more orbitals and electrons, the farther away the outermost electron gets from the nucleus, making it easier to remove an electron from the atom.

Question 6

Define electronegativity

Answer 6

The ability for the atom to hold electrons tightly to itself.

Question 7

Properties of metals

Answer 7

Malleable, high melting point, good conductors of electricity, high density, ductile, etc.

Question 8

Properties of nonmetals

Answer 8

Can be in any form (Solid, liquid and gas), don’t conduct electricity well, aren’t malleable, are not shiny, etc
