Best example of matter

Matter is intensely heated that causes electron released and particle are ionized (electrically charged)

“Matter is Neither created nor destroyed, rather, it is recycled over and over again”

Substances that cannot be broken down into simpler forms by ordinary chemical reactions

• How many elements are there? • Natural ones? • Created under special conditions?

Responsible for more than 96% of the mass of most living organisms

Smallest Particles that exhibit the characteristics of an element

Atoms consists of? - Positively Charged? - Negatively Charged? - Electrically Neutral?

Are smaller compare to other particles, They orbit the nucleus at the speed of light

Have approximately the same mass and clustered in the nucleus
