S1U4L1 MonoIons

CAVA 302 303 S1U4L1 Monoatomic Ions

QuestionAnswer
When an atom loses an electron, the atom has a [...] charge and is called a cation. When an atom loses an electron, the atom has a positive charge and is called a cation.
A positively charged ion is called a [...]. A positively charged ion is called a cation.
You can remember that a cation is positive because the [...]. You can remember that a cation is positive because the 't' in 'cation' looks like the + sign.
In an atom, the valence electrons are those in the [...-most] orbitals. In an atom, the valence electrons are those in the outermost orbitals.
[...] electrons are the ones that participate in forming ions. Valence electrons are the ones that participate in forming ions.
When an atom gains an electron, the atom has a [...] charge and is called an anion. When an atom gains an electron, the atom has a negative charge and is called an anion.
A negatively charged ion is called an [...]. A negatively charged ion is called an anion.
An ion formed from a single atom is called a [...-atomic] ion. An ion formed from a single atom is called a monoatomic ion.
For most metals, the charge of an ion will be the same as the [...] number in a periodic table labeled 1A, 2A, etc. For most metals, the charge of an ion will be the same as the group (column) number in a periodic table labeled 1A, 2A, etc.
Charges on [...] metal ions are harder to predict. Charges on transition metal ions are harder to predict.
Most non metals will gain enough electrons to give them a full [...] of valence electrons. Most non metals will gain enough electrons to give them a full octet of valence electrons.
Hydrogen ions can have a charge of either [...] or [...]. Hydrogen ions can have a charge of either +1 or -1.
