Plants survival depends upon photosynthesis. Plants are the ultimate source of energy for
organisms. Photosynthesis is a process by which plants use the energy from sunlight
Predicting the Reactivity of Elements
Metals have been studied and utilized for a very long time, and we know a great deal
about their reactivity. In general, the reactivity of a metal is related to its ionization
energy. This is because metals tend to lo
Diatomic molecules and Activity Series
Diatomic molecules are elements that form two atom molecules in their natural
form at STP. Remember the phrase BrINClHOF (Br2, I2, N2, CL2, H2, O2, F2)

Building Molecular Models
1) The basic way to find the electron is by using the octet rule. Depending on the
formula, I may make lone pairs or shared electrons alone, so the resulting
molecule/compound has an
Simple Nuclear Reactions Assignment
The presence of gamma rays doesnt affect how a nuclear
equation of alpha or beta decay is balanced because gamma
rays doesn't have an atomic number or mass number,
therefore it wouldn'

Atom the basic unit of matter.
An atom is the smallest particle of an element that still
has all the properties of the element.
Atoms are made up of smaller particles called protons,
neutrons, and electrons. The
