How do atoms achieve stability?
Atoms can achieve stability by sharing electrons.
How does a covalent bond form?
A covalent bond forms when two positive nuclei are held together by their common attraction for a shared pair of electrons.
How does a covalent bond hold the atoms together?
The covalent bond holds the two atoms together by the common attraction both bonded nuclei have for the shared pair of electrons.
What is a shared pair of electrons in a covalent bond attracted to?
In a covalent bond the shared pair of electrons is attracted to both nuclei of the bonded atom.
What is a double covalent bond?
A double covalent bond consists of two shared pairs of electrons.
What is a triple covalent bond?
A triple covalent bond consists of three shared pairs of electrons.
Name the seven elements that exist as diatomic molecules through the formation of covalent bonds.
Fluorine(F2) Chlorine(Cl2) Oxygen(O2) Hydrogen(H2) Nitrogen(N2) Bromine(Br2) Iodine(I2)
What is a molecular formula?
The molecular formula of a molecule shows the number and type of atoms joined together by covalent bonds.
