What is a pure substance? Is a substance in which there is a uniform composition of “particles”. The particles we are talking about are atoms.

What is an element? meet the elements song A substance that Contains only one type of atom. All known elements are organized on the periodic table of elements. atoms and elements

What is a compound? Is a combination of elements that come together through a chemical reaction and becomes something called a molecule.  A molecule is two or more different elements combined in a specific ratio.

What is an atom? The smallest part of an element that has the same properties of that element. In Greek means- “Uncuttable” atom animation

What Is an atom Made of? Protons – Found in the atom’s nucleus and has a positive charge. + Protons

What Is an atom Made of? Neutrons – Found in the atom’s nucleus and has no charge. The nucleus contains most of the atom’s mass What 2 things are found inside the nucleus? Neutrons Protons n Neutrons

Electrons – Found circling the atom’s nucleus. - Each has a negative charge. What Is an atom Made of? Electron -

What is the atomic number? The atomic number is the number of Protons in the nucleus of that atom. All atoms of an element have the same atomic number.
