Elements and Atoms Flashcards
(18 cards)
Nucleus
The Central Part of an Atom Which Contains Both Protons and Neutrons
Transition Metal
Good Conductors of Heat and Electricity. They are Shiny Dense and Strong.
Noble Gase
Nonreactive, Colourless and Usually a Gas at Room Temperature. Located in Group 0 of the Periodic Table.
Ionic Bond
An Electron is Taken From One Atom and Given to Another Which Gives them Opposite Charges Thus Attracting them Together
Isotope
An Atom with the Same Atomic number But a Different Mass Number (An Atom with a Different Number of Neutrons)
Base
An Alkali Before it is in an Aquarius Solution (PH Greater than 7)
Alkaline
A Soft Metal in Group 1 of the Periodic Table. Increasing Reactivity with Increasing Shells
Non-metal
Dull-looking, Brittle and Generally a Poor Conductor of Electricity
Halogen
Coloured Non-metal with Decreasing Reactivity with More Shells. Located in Group 7 of the Periodic Table.
Electron
Negatively Charged Sub-atomic Particle with a Mass Close to Zero
Element
Atoms With the Same Atomic Number
Metal
Elements Which Form Positive Ions When they React
Acid
A Substance With a PH Less than 7
Alkalies
An Alkali Forms an Aquarius Solution with a PH Greater than 7
Neutron
Neutrally Charged Sub-atomic Particle With a Mass of 1
Shell
A magnetic orbit Around a Nucleus of Which an Electron Resides in
Proton
Positively Charged Sub-atomic Particle with a Mass of 1
Covallent Bonds
A Bond Between Non-metals Where Electrons are Shared to Fill the Shells
