Van der Waals Forces
A slight attraction that develops between the oppositely charged regions of nearby molecules.
What three sub atomic particles make up atoms?
The subatomic particles that makeup atoms are protons, neutrons and electrons.
What are the two main types of chemical bonds?
The main types of chemical bonds are ionic bonds and covalent bonds
How are all of the isotopes of an element similar?
Because they have same number of electrons, al isotopes of an element have the same chemical properties
Why do all isotopes of an element have the same chemical properties? In what way do isotopes of an element differ?
Because they have the same number of electrons, all isotopes of an element have the same chemical properties
What is a covalent and ionic bond?
A covalent bond forms when electrons are shared between atoms. An ionic bond is formed when one or more electrons are transferred from one atom to another.
