The Atom Notes 9-12-17

4 Major Facts About Atoms The Atom Notes 9-12-17 4 Major Facts About Atoms Atoms are the building blocks of matter Atoms make up everything Atoms have the same number of protons and electrons If the number of protons and electrons do not equal each other, then a charge is present in the atom

4 Major Facts About Atoms The Atom Notes 9-12-17 Have a positive (+) charge Located inside nucleus The size = 1 amu Determines the identity of the atom; it is the atomic number 4 Major Facts About Atoms Atoms are the building blocks of matter Atoms make up everything Atoms have the same number of protons and electrons If the number of protons and electrons do not equal each other, then a charge is present in the atom

4 Major Facts About Atoms The Atom Notes 9-12-17 Have a neutral charge Located inside the nucleus The size = 1 amu Related to the atomic mass number Holds the nucleus together 4 Major Facts About Atoms Atoms are the building blocks of matter Atoms make up everything Atoms have the same number of protons and electrons If the number of protons and electrons do not equal each other, then a charge is present in the atom

4 Major Facts About Atoms The Atom Notes 9-12-17 Have a negative (-) charge Found outside the nucleus Size = 0 amu Responsible for atoms reactivity 4 Major Facts About Atoms Atoms are the building blocks of matter Atoms make up everything Atoms have the same number of protons and electrons If the number of protons and electrons do not equal each other, then a charge is present in the atom

The Parts of an 9-12-17 Atom + = Protons Positive charge [ ] = Nucleus Found in nucleus [ ] = Nucleus Consists of protons and neutrons Found at the center of the atom 0 = Neutrons Neutral charge Found in nucleus - = Electrons Negative charge Found in electron shells (a.k.a. energy levels) O = Energy Levels Surround the nucleus Contain electrons Amount of electrons in each ring: 1st Ring: 2 electrons 2nd Ring: 8 electrons 3rd Ring: 18 electrons - = Valance Electrons Negative charge Found in outermost energy level (last one) Determine an element’s reactivity
