Atomic structure
Cards in this deck (15)
- 1what makes up an Atom?The nucleus made up of protons and neutrons
The electrons that move around the nucleus in shells - 2What are the mass of Electrons Protons NeutonsElectron = 0
Proton = 1
Neutron = 1 - 3What are the charges for Proton Neutron ElectronProton = +1
Neuton = 0
Electron = -1 - 4why would an atom have a charge of -2?because they have 2more elections than protons
- 5how many elections can a atom have in one shell?8 apart from the innermost the only has 2
- 6always have the same number of elections and protonsAtomic number shows the number of Protons
- 7the mass number shows the total number of protons and neutronsexample
Mass number 12
element Carbon-12
Atomic number 6 - 8there can be different numbers o neutrons from protonsthis can be calculated by subtracting the atomic number form the mass number
- 9Elements consist of atoms with the same atomic numberthe element is decided by the number of protons In the nucleus
- 10A atom with one proton in its nucleus is hydrogen and a atom with 2 is heliumthere are roughly 100 different elements
- 11Atoms can be represented by symbolsCarbon = C
Magnesium = Mg
sodium = Na - 12isotopes are elements with different amounts of neutronsCarbon 12 in the element Carbon 13 is the isotope
- 13Relative atomic masssum of (isotope abundance x isotope masses number )
-------------------------------------------------------
sum of abundance of all the isotope - 14compoundscompounds are Meade up of different elements when elements react the product will be a compound eg iron + oxygen = iron oxide
- 15compounds are made of 2 or more elements
