Flashcards in Elements and Atoms Deck (18):
1

Nucleus

The Central Part of an Atom Which Contains Both Protons and Neutrons

2

Transition Metal

Good Conductors of Heat and Electricity. They are Shiny Dense and Strong.

3

Noble Gase

Nonreactive, Colourless and Usually a Gas at Room Temperature. Located in Group 0 of the Periodic Table.

4

Ionic Bond

An Electron is Taken From One Atom and Given to Another Which Gives them Opposite Charges Thus Attracting them Together

5

Isotope

An Atom with the Same Atomic number But a Different Mass Number (An Atom with a Different Number of Neutrons)

6

Base

An Alkali Before it is in an Aquarius Solution (PH Greater than 7)

7

Alkaline

A Soft Metal in Group 1 of the Periodic Table. Increasing Reactivity with Increasing Shells

8

Non-metal

Dull-looking, Brittle and Generally a Poor Conductor of Electricity

9

Halogen

Coloured Non-metal with Decreasing Reactivity with More Shells. Located in Group 7 of the Periodic Table.

10

Electron

Negatively Charged Sub-atomic Particle with a Mass Close to Zero

11

Element

Atoms With the Same Atomic Number

12

Metal

Elements Which Form Positive Ions When they React

13

Acid

A Substance With a PH Less than 7

14

Alkalies

An Alkali Forms an Aquarius Solution with a PH Greater than 7

15

Neutron

Neutrally Charged Sub-atomic Particle With a Mass of 1

16

Shell

A magnetic orbit Around a Nucleus of Which an Electron Resides in

17

Proton

Positively Charged Sub-atomic Particle with a Mass of 1

18

Covallent Bonds

A Bond Between Non-metals Where Electrons are Shared to Fill the Shells
