Compounds and Molecules Nick Scott Flashcards
What is a chemical structure?
A chemical structure is the arrangement of atoms in the molecule.
What is a chemical bond?
A chemical bond is the attractive force that holds atoms together.
What is a bond length?
Bond length is the distance between the nuclei of two bonded atoms.
What is a bind angle?
A bond angel is the angle formed by two bonds to the same atom.
What is a hydrogen bond?
Hydrogen bond is one oxygen atom attracted to two hydrogen atoms.
What is an ionic bond?
An ionic bond is a bond formed by the attraction of two different charged ions.
What is a formula unit?
A formula unit is the formula of the molecule.
What is a metallic bond?
A metallic bond is a bond formed by the attraction between positively charged metal ions and electrons.
What is a covalent bond?
A covalent bond is a bond formed when atoms share more or one pairs of electrons.
What is a nonpolar covalent vond?
A nonpolar covalent bond is a bond when electrons are shared equally.
What is a polar covalent bond?
A polar covalent bond is when the shared electrons are attracted to the nucleus of one atom more then the other.
What is a polyatomic ion?
A polyatomic ion is an ion made of two or more atoms.
What is a empirical formula?
A empirical formula is the composition of a compound in terms of the relative numbers and kinds of atoms in the simplest ratio.
What is a molecular formula?
A molecular formula is a chemical formula that shoes the number and kinds of atoms in a molecule, but not the arrangement of the atoms.
What is an organic compound?
An organic compound is a covalently bonded compound that contains carbon.
