 Atom | the smallest part of an element that maintains the properties of the elment |
| Democritus | named the atom for atomos(indivisible) |
| Modern Atomic Theory | Electrons are in electron clouds but we are not sure of their exact location |
| Proton | mass=1 amu charge= positive location= nucleus |
| Neutron | mass= 1 amu charge=neutral location= nucleus |
| Electron | mass=too small to measure charge negative location= in electron clouds |
| Isotopes | Atoms of the same element that have the same number of protons but a different number of neutrons. |
| How many electrons in Alkali metals? what family? | 1 and first |
| how many electrons in Alkaline earth metals?what family? | 2 and second |
| How many electrons in boron? what family? | 3 and 13th |
| how many electrons in carbon? what family? | 4 and 14th |
| how many electrons in nitrogen?what family? | 5 and 15th |
| how many electrons in oxygen? what family | 6 and 16th |
| how many electrons in the hallogen family(saltmakers)? what family? | 7 and 17th |
| how many electrons in the noble gases? what family? | full either k=2 or l/m=8 and 18th |
| how many energy levels are there? | 7/ K-Q |
| how many electrons does it take for the k shell to be full? | 2 |
| how many electrons does it take to fill shells L-Q ? | 8 |
| Metals | to the left of the zigzag line |
| metalloids | 8/ touches zigzag line excluding aluminum |
| nonmetals | to the right of the zigzag line |
| Same properties | same number of shells in the outer energy level |
| Ion | an atom that has a positive or negative chargethrough the transfer of electrons |
| Ionic bonding | bond that forms when electrons are transferred from one atom to another, which results in a positive ion and a negative ion |
| atoms get larger when: | going down a family |
| atoms get smaller when: | going across a period |
| Covalent bonding | a bond formed when atoms share one or more pairs of electrons |
