this is data collected during an experiment that is counted, such as numbers
what is quantitative data
this is found in the nucleus of an atom but has no charge
neutron
Neon has an atomic mass of
10
1,000,000,000,000,000
1
this is the smallest building block of life
what is an atom
these have a positive charge
protons
Ca has this many protons
20
0.00345
this type of data contains characteristics that cannot be counted
what is qualitative data
these are elements of the same kind but have different numbers of neutrons. Example: Carbon 12, and Carbon 13
what are isotopes
hydrogen has this atomic mass
1 proton
4.2311156
8
the smallest form of a substance that has chemical and physical properties.
what is a molecule
this is found outside the nucleus of an atom in orbital shells
electron
how do you find the number of neutrons in an element?
what is subtract the atomic number from the atomic mass
1500
daily double
2
this is released when an electron jumps an energy level and then falls back down to its original energy level.
what is spectra
this determines the atomic mass of an element
daily double
what is number of protons
