Covalent Bonds 3

Covalent Bonds stack 3

TermDefinition
As a bond between a hydrogen atom and a sulfur atom is formed, are the electrons shared or transferred to form a covalent or ionic bond? The bond between a hydrogen atom and a sulfur atom is non-polar covalent, so the electrons are shared.
Why do elements share electrons? The atoms of some elements share electrons because this gives them a full valence shell.
T or F: The chemical bond formed when 2 atoms share electrons is called a covalent bond. True
Ionic compounds are _______ at room temperature that have one ion strip the electron(s) from the other elements' electron cloud. solids
The sharing of electrons is called a _______. covalent bond

A ______ ______ is formed when a pair of electrons is shared between tow, usually nonmetal, atoms. covalent bond
It is helpful to show the pair of electrons in a covalent bond as a ______. dash mark - as in H-H for hydrogen
Structural formula is Showing the pair of electrons in a colvalent bond as a dash mark. -
_______ formulas are the chemical formulas that show the arrangements of atoms in molecules. Structural
Structural formulas are the ________ formulas that show the arrangements of atoms in molecules. chemical
The dashes ______ indicate a pair of shared electrons, NEVER ionic bonds. always
The dashes always indicate a pair of shared electrons, ______ ionic bonds. never
Group 4A-7A nonmetal elemnts are prone to form __ ___. covalent bonds
