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 |
