Chemical Formula Numbers
Where is the coefficient in a chemical formula located?
The coefficient in a chemical formula is located to the left of the first element in the formula.
What is an ion with more electrons than protons called?
An ion with more electrons than protons is called an anion.
What two types of elements are in an ionic bond? (metal/nonmetal)
A metal and a nonmetal are in an ionic bond.
What prefix in the word "subscript" indicates that the number is written below an element's symbol?
The prefix "sub-" indicates that the number is written below an element's symbol.
Opposite of: Subscript
Superscript
What do oxidation numbers indicate?
Oxidation numbers indicate the number of electrons an atom has lost, gained, or shared to become stable.
What is an ion with more protons than electrons called?
An ion with more protons than electrons is called a cation.
What two types of elements are in a covalent bond?
Two nonmetals are in a covalent bond.
What prefix in the word "superscript" indicates that the sign is written above the element's symbol?
The prefix "super-" indicates that the sign is written above the element's symbol.
Opposite of: Anion
Cation
What does the subscript in a chemical formula indicate?
The subscript in a chemical formula indicates the number of atoms of an element in a molecule.
Why aren't neutral atoms considered ions?
Neutral atoms aren't considered ions because they have the same number of protons and electrons. They have no charge.
What is the force that holds atoms together in a compound called?
The force that holds atoms together in a compound is called a chemical bond.
What prefix in the word "coefficient" indicates that the number is written beside the first element's symbol?
The prefix "co-" indicates that the number is written beside the first element's symbol.
Opposite of: Polar Molecule
Non-polar Molecule
What do coefficients in a chemical formula indicate?
Coefficients in a chemical formula indicate the number of units of each substance taking part in a reaction.
What is an atom that has the same number of protons and electrons (not an ion)?
An atom that has the same number of protons and electrons is a neutral atom.
The force of attraction between the opposite charges of the ions in an ionic compound is called an ionic bond.
What suffix in the word "cation" indicates that there are either more electrons than protons or more protons than electrons in the atom?
The suffix "-ion" indicates that are either more electrons than protons or more protons than electrons in the atom.
Opposite of: Ionic Bond
Covalent Bond
Where is a superscript located and what does it indicate?
A superscript is located to the top right of an element, and indicates whether it is positive or negative.
What is the definition of an ion?
An ion is an atom that has either more protons than electrons or more electrons than protons.
What is a covalent bond?
A covalent bond is the attraction that forms between atoms when they share electrons.
What prefix in the word "anion" indicates that there are more electrons than protons in the atom?
The prefix "an-" indicates that there are more electrons than protons in the atom.
Opposite of: Ion
Neutral Atom
