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