Electron
configuration
The electron configuration
of an atom is a form of
notation which shows how
the electrons are
distributed among the
various atomic orbital and
energy levels. The format
consists of a series of
numbers, letters and
superscripts as shown
below.
characteristics
groups
Each set of elements
appearing in the vertical
column of a periodic table
is called a Group and
represents a family of
elements that have similar
physical and chemical
properties.
atoms
The atom is a basic unit of matter
that consists of a dense, central
nucleus surrounded by a clod of
negatively charge electrons .
covalent bonds
Covalent bonds represent
chemical potential energy
that can be used in
biological reactions. a type
of chemical bound
characterized by the
sharing of a pair of
electrons between two
atoms. The electron pair
interacts with the nuclei of
both atoms.
ionic bonds
Ionic bonds are a type of
electrostatic bond between
two atoms that is weaker
than covalent bonds, but
usually stronger than
hydrogen bonds They are
formed from the mutual
attraction of ions. Typical
participants in an ionic
bond are a metal and a
non-metal, such as sodium
or chlorine.
energy
There are seven types of
energy.
1.
Heat
2.
Light
3.
Motion
4.
Electrical
5.
Chemical
6.
Nuclear energy
7.
Gravitational
These seven types of
energy are that we use
every day. From
How energy is
formed.
The top two ways that
energy is formed are solar
and hydro.
Solar energy, radiant light
and heat from the sun
producing energy.
Hydro energy, is simply
energy that is taken from
water and converted to
electricity.
work
Work is defined as the
result of applying a force to
an object in order to move
it a certain distance. In
other words, work equals
force times distance. Work
is always against some
resistance.
speed
the rate of something
moves, happens, or
functions.
acceleration
the rate at which something
increases in velocity
increase in rate of
progress an increase in the
rate at which something is
happens or develops
simple machines
There are six simple machines
1.
A lever is a board or bar
that rests on a turning
point. This turning point is
called the fulcrum.
2.
It is a flat surface that is
higher on one end. You
can use this machine to
move an object to a lower
or higher place.
3.
The wheel& axle is a rod
that goes through the
wheel.
4.
A screw is a simple
machine that is made from
another simple machine. It
is actually an inclined
plane that winds around
itself.
5.
A wedge is made up of
two inclined planes.
6.
The rope fits on the groove
of the wheel.
Heat transfer
is the transfer of thermal
energy from one region of
matter or a physical system
to another. There are five
kinds of heat transfer.
waves
To move freely back and
forth or up and down in
the air, as branches in the
winds and, make a signal
with an up-and-down or
back-and-forth movement
of the hand or an object
held in the hand
Look hard you can see a
wave.
sounds
is a medical wave that is
an oscillation of pressure
transmitted through a
solid, liquid ,or a gas
composed of frequency
within the range of hearing
and of a sertine level of
sound
color
Is the visual perceptual
property of in humans to
the categories called red,
green, blue and others.
Color corresponding
Electricity
is a general term describing
a variety of strong resulting
from the presence and flow
of electric charge. These
include many easily
recognizable such as
lightning and static
electricity.
lightning
is an atmospheric discharge
of electricity. it also has
three steps to form.
1.
It gathers protons and
electrons.
2.
Then it separates
3.
Lastly it discharges.
