| Question | Answer |
|---|---|
| Matter | Anything that takes up space and has Matter |
| Mass | The material that Mass is made up of. |
| Volume | how much room Matter makes up |
| Proton | Particles of an atom that positives change inside the nucleus the nucleus |
| neutron | a part of the atom found in the very middle and it is neutral |
| Periodic table | a grid that identify and classify the element into periods and groups by their physical property's |
| Density | The amount of mass in a specific volume of space |
| nucleus | Very small enter core of an atom and is neutral |
| Periods | how rows that tell how many energy levels each substance has |
| Atom | The smallest part of an element, the building block's of all matter |
| Electron | particle of an atom with a negative charge, moves around the nucleus and has an attractive force that allows it to bond with other atoms |
| Element | the simplest substance that can not be broken down |
| Columns | columns that tell how many valence electrons each element has |
| Valence Electrons | the electrons that move on the outer shell |
| atomic number | how many protons a element has inside the nucleus |
| atomic mass | the mesuremnet of mass |
| Chemical property | the ability of substances to combine with one another |
| Physical property | the state of matter and appearance of a substance |
| Ionic bond | when elements either lose or gain an electron during bonding |
| convalent bond | when elements share electrons during bonding |
| reaction | element bond together trough the attractive force |
| compound | two or more elements combine together trough a specific ratio |
| Mixture | Two or more substances combine to together keeping their original properties |
| Noble gasses | They are the most stable elements because they have eight electrons in their outer shell |
| Halogens | They are very reactive bonding with all of the elements in group #1 |
| Alkali Metals | they are not very reactive because they only have one valence electrons |
| Metalloids | Elements between metals and non metals that can react either way they have 3-7 valence electrons |
