Chemical Bonding Flashcards
Nucleus
Has positive protons and neutral neutrons
Negative electrons
Circle the nucleus shells
Atomic number
The number of protons in an atom
Mass number
The number of protons + neutrons
Compound
When two or more atoms of different elements have a chemical bonding joining together.
Octet rule
Alone will bond together so that each atom attains an electron arrangement with 8 electrons in its outermost shell
Ionic bonding
One atom gives electrons and the other atom takes electrons to get full outer shell
Covalent bonding
Both atoms share electrons to get a full outer shell
Single covalent bonds
Occurs when atoms share one pair of electrons
Double covalent bonds
Formed when atoms share two pairs of electrons
Atom
An atom is the smallest part of an element which still has the properties of that element.
