2. 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.

3. 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.

4. atoms The atom is a basic unit of matter that consists of a dense, central nucleus surrounded by aclod of negatively charge electrons .

5. 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.

6. 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.

7. energy There are seven types of energy. Heat Light Motion Electrical Chemical Nuclear energy Gravitational These seven types of energy are that we use every day. From

8. 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.

9. 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.

10. speed the rate of something moves, happens, or functions.

11. 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

12. simple machines There are six simple machines A lever is a board or bar that rests on a turning point.  This turning point is called the fulcrum. 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. The wheel& axle is a rod that goes through the wheel. A screw is a simple machine that is made from another simple machine.  It is actually an inclined plane that winds around itself. A wedge is made up of two inclined planes.  The rope fits on the groove of the wheel.

13. 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.

14. 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.

15. 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

16. color Is the visual perceptual property of in humans to the categories called red, green, blue and others. Color corresponding

17. 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.

18. lightning is an atmospheric discharge of electricity. it also has three steps to form. It gathers protons and electrons. Then it separates Lastly it discharges.
