Atoms Ions and Reactions Flashcards
What is inside a atom
a nucleus with protons and neutrons and electrons orbiting it
what charges are protons neutrons and electrons
Protons- positive
Neutrons- neutral
Electrons- negative
what are the 3 main differences between protons electrons and neutrons
- charge
- mass
- location
what is an element
a substance made up of only one type of atom
what is the mass number
number of particles found in nucleas (protons + neutrons)
what is an atomic number
number of protons in nucleus and electrons orbiting nucleus
how to calculate number of neutrons
mass number - atomic number
what is the outer shell called in element
valence shell
description of metal elements
Metal elements lose electrons to become positively charged and are called a CATION
description of non-metal elements
non-metal elements gain electrons to become negatively charged and are called ANIONS
what is a monoatomic ion
an ion made of one type of atom
what is an ionic compound
metal ion + non metal ion = ionic compound
what is a chemical reaction
process that produces a chemical change to one or more substances
what is a reactant
chemicals reacting together
what is a product
chemicals produced by reactants
