2.3 Formation And Function Of Atoms Flashcards
Interaction between valence electrons are held by what?
Chemical bonds
Atoms either _____ or _____ valence electrons.
Atoms either share or transfer valence electrons.
What is a covalent bond?
A covalent bond is the sharing of valence electrons.
What is a molecule?
A molecule is two or more atoms held together by a covalent bond.
What is a single bond?
A single bond is a pair of shared electrons
What is a double bond?
A double bond is two pairs of shared electrons
What is a valence?
Valence is the bonding capacity of an atom which usually equals the number of unpaired electrons in the valence shell.
What is Electronegativity?
Electronegativity is how strong an atoms attraction for a shared electron.
What is a Nonpolar covalent bond?
The equal sharing of an electron in the valence shell.
What is a Polar covalent bond?
A polar covalent bond is the unequal sharing of an electron in the valence shell.
In a polar covalent bond, which atom receives a slightly negative charge and which receives a slightly positive charge?
In a polar covalent bond, the dominant atom receives a negative charge and the submissive atom receives a slightly positive charge.
What is an Ionic bond?
An Ionic bond is a chemical bonding resulting from the attraction of oppositely charged ions.
A charged atom is called?
A charged atom is called an Ion
A positively charged atom is called?
A positively charged atom is called a cation.
A negatively charged atom is called?
A negatively charged atom is called an anion.
