Chemical Bonding Flashcards
Nucleus
Has positive protons and neutral neutrons
Atom
Is the smallest part of an element
Electrons
Circle the nucleus in shells
Atomic numbers
The numbers of protons in an atom
Ass number
Is the number of protons plus neutrons
Compounds
Is when 2 or more atoms with different elements have a chemical bond joining them together
Octet rule
Atoms will bond together so that each atom attains an electron arrangement with 8 electrons In It’s outermost shell
Iconic bonding
Is when one atom gives electrons and the other atoms takes electrons to get a full outer shell
Covalent bonding
Is when both atoms share electrons to get a full outer shell
Single convalent bonds
Occur when atoms share one pair of electrons
Double covalent bonds
Is formed when atoms share two pairs of electrons
