Subatomic Particles, Relative Mass, Relative Charge, Istotopes, Mass Number, Atomic Number Flashcards
Find out the relative mass and relative charge of particles find out how to work out the mass and define isotopes
what is a protons relative mass and relative charge
relative mass 1 relative charge +1
what is the relative mass and relative charge of a neutron?
relative mass=1. relative charge=0.
what is the relative mass and relative charge of an electron?
relative mass=0 relative charge= -1
if an atom loses one or more electrons it becomes a ?????
positively charged ion
if an atom gains one or more electrons is becomes a ????
negatively charged ion
the number of elections in an atom is the same as the number of ????
Protons
what is an isotope
atoms of an element with different number of neutrons. they have the same proton number (and electron number) but different mass numbers
on the periodic table, what does the top number mean?
relative Atomic mass
on the periodic table what does the bottom number mean?
Atomic Number
where are the metals on the periodic table?
on the left hand side and in the middle (transition metals)
where are the non metals
on the right hand side
how many electrons can the innermost shell have
2 electrons
how many can the other shells have
8 electrons
what does the atomic number tell you?
how many electrons the element has him it’s electronic configuration.
what does the period tell you?
how many occupied shells the element has
