formations of ion and ionic compound Flashcards
Inside the nucleus are
protons and neutrons
A proton is a _ charged particle,
positively-charged
a neutron is a _ charged particle.
neutrally-charged
The number of protons in an element corresponds to the atomic number_ of an element.
( Z)
The sum of protons and neutrons of an element is equal to the mass number_
( A )
Revolving around the nucleus are negatively-charged particles called _
electrons
When an atom has an equal number of protons and electrons, the atom is considered a _
neutral atom
When an atom gains or loses an electron, the atom has a _
net electric charge
electrically charged atom or group of atoms is called an _
ion
When the ion is composed only of one atom, it is called a _
monoatomic ion
When the ion is composed of two or more atoms, it is called a _
polyatomic ion
An ion can be classified as a _ or a _
cation and anion
cation: When an atom loses an electron, there will be more _
protons than electron
The atom becomes a positively charged ion called a _
cation
have a greater tendency to lose electrons.
metals
