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
