Vocabulary
This is what ionic bonds do with their electrons
What is transfer completely (gain or lose)?
This is the type of substance water is.
Polar
If an atom gains an electron, it has this charge.
What is negative?
This is what happens in a covalent bond when the atoms have an electronegativity difference of less than 0.4.
What is they share the electrons equally and form a nonpolar covalent bond?
These are the types of atoms that are in an ionic bond.
What are metal and nonmetal?
This is what type of substance most of the ingredients in your lip balm are.
What are nonpolar?
This term means electron loving and increases the higher up and to the right you go on the periodic table.
What is electronegativity?
Covalent molecules such as Ethylene (C2H4) have this type of melting and boiling points.
What is LOW? (because the the electrons are loosely shared it is easier to separate the atoms in a molecule)
Because sulfur that gains two electrons it has this charge.
What is negative two?
This is why polar molecules have a higher melting point than nonpolar molecules.
What is the atoms have partial charges that stick together between molecules?
This is the type of bond between two metals that has a high melting point due to a sharing sea of electrons.
What is metallic bond?
Covalent bonds occur between these types of substances.
What are two nonmetals?
This is the charge of potassium once it is a stable ion.
What is +1?
These are the two intermolecular forces that explain why even though water is small it acts like a large molecule and has a high melting point for a covalent substance.
What are dipole-dipole interactions and hydrogen bonds?
Lithium gives up an electron to chlorine to obey this rule.
What is the octet rule?
If the electronegativity difference is between 0.5 and 1.0 then the electrons will be shared unequally and form this type of covalent bond.
What is polar covalent?
What is the molecular formula if you make a molecule made of calcium and chloride?
CaCl2
This is why oil and water don't mix.
What is water molecules are polar (having positive and negative ends) and strongly attract each other, while oil molecules are non-polar and hydrophobic ("water-fearing") causing them to repel?
