What element has 3 protons and 3 electrons?
The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.
Why is each isotope's mass multiplied by the isotope's percent abundance?
That is done to calculate the weighted average.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
Calculation of the atomic weight of an element having many isotopes:ia - atomic mass of the isotope a x percent concentration of the isotope in the elementib - atomic mass of the isotope b x percent concentration of the isotope in the elementic - atomic mass of the isotope c x percent concentration of the isotope in the element...........................................................................................................................iz - mass of the isotope z x percent concentration of the isotope in the elementMake the sum: I = ia + ib + ic + ..... izThe atomic weight of the element is: I/100 (the term weight is recommended by IUPAC in this case).
