Ions and Compounds Flashcards
It is may be an atom or group of atoms that has gained or lost one or more of its valence electrons.
Ion
TRUE OR FALSE
An ion is charged because its number of electrons is EQUAL to its number number of protons.
FALSE
Not Equal
It can require a net positive charge or a net negative charge depending on whether the number of electrons is greater or less than the number of protons in an atom.
Atom
It is an ion that carries a net positive charge and it loses an electron.
Cation
It is an ion that carries a net negative charge and it gains an electron.
Anion
It is an ion that contains only one type of atom.
Monatomic Ion
It is an ion that contains two more types of atoms.
Polyatomic Ion
It is made up of two or more atoms with a definite arrangement that are held together by a chemical bond.
Molecule
What are the four common properties of ionic compounds?
(1) Have crystalline structures.
(2) Have high boiling points and high melting points.
(3) Soluble in water.
(4) Good conductors of electricity.
It is the total number of electrons that an atom gains or loses to form a chemical bond with another atom to achieve a neutral state again.
Oxidation Number / Oxidation State
These are elements with different oxidation numbers.
Transition Elements
What are the four common properties of covalent compounds?
(1) Some are solids but most are liquid and gases at standard conditions.
(2) Have low boiling points and low melting points.
(3) Soluble in water.
(4) Poor conductors of electricity.
It is a type of bond that occurs when two atoms equally share electrons.
Nonpolar Covalent Bond
What nonmetal element has a higher electronegativity value than hydrogen, which is a metal?
Fluorine
It is when the electrons are not equally shared because one atom spends more time with the electrons than the other atom.
Polar Covalent Bond
