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 |
