Vocabulary for Matter and Elements

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
