Ions Flashcards
An ——— is an electrically charged atom or group of atoms.
ion
An atom that loses some of its electrons becomes ———.
positively charged
An atom that loses some of its electrons becomes positively charged.
When this happens, the number of protons becomes ——— than the number of electrons.
greater
A positive ion is called a ———.
CATION
An atom that loses an electron will still have the same atomic number and mass number.
CATION
To form a cation, one or more electrons are ——— from a neutral atom or group of atoms.
removed
An atom gains excess electrons becomes ———.
negatively charged
An atom gains excess electrons becomes negatively charged.
When this happens, the number of protons is ——— than the number of electrons in the particle.
less
A negative ion is called an ———.
ANION
An atom that gains extra electrons will have the same mass number and atomic number as the ion that was formed.
ANION
In forming anion, one or more electrons are ——— to a neutral atom or group of atoms.
added
In general, formations of ions from elements are ——— to their group numbers in the periodic table.
related
For an element belonging to Group IA, Group lIA, or Group IllA to become a ———, it ——— a number of electrons ——— to its group number.

loses
equal
In forming ———, an element belonging to Group VA, Group VIA, or Group VIIA ——— a number of electrons ——— to the number to be added to the group number to make a total of ———.
