Und wu me the #protons for the same element most be the
same. the protons determine what the element identity will be atoms whose number of neurons are
more than the protons are unstable and can become radioactive carbon 14 is a radioactive case
atomic mass
(p + n)
atomic charge
(charge p + charge 8-)
neutral elements have no charge because
the #protons = #electrons
atomic #
(hp)
for each of the following neutral stoms, create the isotope symbol. you will need your periodic table to
look up the atomic number,
1. lead-210
2. sodium-22
3. uranium-236
4. sulfur-32
5.
iron-60
6. boron-11
for each of the following generic isotope symbols, look up the name of the element
from its atomic number and write its name.
