Atoms&Elements Flashcards
How are the number of protons and electrons related?
The number of protons = the number of electrons ( atoms have no overall charge )
How many types of atom does and element have?
An element has only 1 type of atom
How are elements represented and where are they found?
Elements are shown by a symbol beginning with a Capitol letter
What is an atom made up of
Atom contain a nucleus ( made of protons and neutrons) and electrons which orbit around in shells
Do metal atoms lose or gain electrons?
Metal atoms lose electrons becoming positive in charge
cations
Do non-metals atoms lose or gain electrons ?
Non-metal atoms gain electrons becoming negative in charge
anions
What arse cations?
Atoms which lose electrons which have a positive charge ( less electrons than protons)
What are anions?
Anions are atoms which gain electrons which have a negative charge
( having more electrons than protons)
