1 d) The Periodic Table

Question 1

Group

Answer 1

Vertical column in the Periodic Table. All elements in the same group have the same number of outer shell electrons and similar chemical properties.

Question 2

Inert

Answer 2

Unreactive

Question 3

Period

Answer 3

Horizontal row in the Periodic Table. All elements in the same period have the same number of occupied shells.

Question 4

Electronic Configuration

Answer 4

How electrons are arranged in the shells in an atom.

Question 5

Isoelectronic

Answer 5

Same number of electrons

Question 6

Noble Gas

Answer 6

Group 0 or 8 on the Periodic Table

Question 7

Octet Rule

Answer 7

Atoms generally lose, gain or share electrons in order to have eight electrons in their outer shell (except the first shell which is full with 2).

Question 8

Periodic Table

Answer 8

Table in which elements are arranged in order of increasing atomic number (and in terms of chemical and physical properties).

Question 9

Shells

Answer 9

Where electrons are found outside the nucleus (also called energy shells).

Question 10

Shielded/Screened

Answer 10

Electrostatic force of attraction on an electron from the nucleus is offset by inner shell electrons (inner electrons shield/screen the outer ones).
