Parts of An Atom

anion - definition

A negatively charged ion

cation - definition

A positively charged ion

covalent bonding - definition

A type of atomic bonding where bonds formed when atoms share one or more pairs of electrons

metallic bonding - definition

A type of atomic bonding where positively charged metallic ions, are surrounded by a sea of electrons

ionic bonding - definition

A type of atomic bonding where the bonds that forms as a result of the attraction between positively and negatively charged ions

Ion

An atom or group of atoms that has a positive or negative charge. Because of the number of electrons and protons are not the same.

Isotope

An atom with a varying number of neutrons Atoms of the same element that have different numbers of neutrons

Atomic Bonding

Atomic bonding is chemical bonding. Chemical bonding is the physical process that is responsible for the interactions between atoms and molecules. Different types include: covalent, ionic, metallic, etc.

atom

Basic unit of matter that retains all the properties of the element

Nucleus

Center of an atom, that contains protons and neutrons

Electron's charge

Negative

Electron

Negatively charged part of an atom, is responsible for bonding

Neutron's charge

Neutral

Neutron

Neutral part of an atom, holds the nucleus together since the protons would naturally want to repel each other

Atomic number

Number of protons in the nucleus of the atom, in an neutral atom it is also the number of electrons

Energy Level

Path around the nucleus, where the electrons reside

Proton's charge

Positive

Proton

Positively charged part of an atom, gives the atom it's identity

Parts of the nucleus

Protons and neutrons

Relative Atomic Mass

The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.
