Vocabulary for Matter and Elemenets
| Term | Definition |
|---|---|
| Matter | Any thing that has mass and takes up space |
| Mass | Material that matter is made up of |
| Volume | The amount of space that matter occupies is called its volume |
| Density | the degree of compactness of a substance |
| Atom | the building blocks,smallest part of an element |
| Electron | Particle of an atom that has negative charge located inside the nucleus that has a attractive force that follows to bond with other atoms creating everything in the whole entire universe |
| Proton | Particle of an atom with no change inside the nucleus |
| Neutron | particle of an atom with a neutral and no charge along with the proton |
| Periodic Table | a grid that identifies and classifies all the elements by their chemical and physical properties |
| Periods\Rows | rows that tell how many energy levels each element has for the electrons to move around |
| Groups\Columns | columns that can tell how many valence electron that each has/ the number in thee outer shell hat move around |
| Valence Electrons | The energy level of a atom/ the outer shell |
| Atomic Number | how many protons an element has inside the nucleus/ usally a number of electrons or neutrons |
| Atomic Mass | the measure of mass a element atoms |
| Chemical Property | ability of substances to combine with one other substance |
| Physical Property | a state of matter and app of substance |
| Ionic Bond | when elements lose or gain an electron |
| Covalent Bond | when elements share electrons during bonding |
| Chemical change | elements bond together through attractive force |
| Compound/Molecule | two or more elements bonded together to create a whole new substance |
| Mixture | two or more substance combined together and the substance stays the same |
| Nobel gases | elements in group #18 that are most stable elements |
| Halogens | elements in group #17 they are reactive bonding easily |
| Alkali Metals | elements in group #1 they are very bonding because there are 7 valence |
| Metelloids | a element between metals and no metals that have 3-7 valence electrons |
| Exothermic | Chemical reaction that releases energy |
| Endothermic | Chemical change that absorbs/and or takes in |
