Peroidic table

vocabulary for matter and elements

QuestionAnswer
Matter is everything with mass and takes up space.
Mass is the measure how much matter something has.
Density relates the mass of a given volume.
Volume is the amount of space matter takes up.
Atom smallest part of an element, building blocks of all matter.
Electron particle of an atom that surrounds the nucleus has an attractive force.
Nuetrons have no charge/nuetral
Periodic Table grid-like chart that sorts out all of the worlds elements.
Element cannot be broken down makes all matter
Periods/Rows tells how many energy levels of electron in an element
Groups or family/columns columns that tell how many electrons are on the outer shell
Valence electons electrons on the outer shell
Atomic number tells how many protons an element has inside it
Atomic mass tells how much mass an element has in its atoms
Chemical properties when substances combine forming a whole new substance
Physical properties describes the state of matter and appearance of an object
Ionic bond when elements lose or get electrons while bonding together
Covalent bond when elements share electrons while bonding together
Chemical change / reaction when elements bond by the attractive force of electrons creating a reaction
Compound/Molecule two or more elements chemically combined creating a new substance
Mixture two or more substances combined not forming a new substances
Nobel Gases Every element in the 18th group because of the number of electrons in the outer shell (8) also most stable
Halogens Every element in the 17th group because of the number of valance electrons in the outer shell (7) very reactive
Alkali Metals Every element in the 1rst group are very reactive and only one valance electrons
Metalloids elements that are metals and non metals that react either way they have 3-7 valance electrons
