Consider the predominant form of sodium atoms in nature, which has 11 protons, 11 neutrons, and 11 electrons. Using one sentence for each of the following changes, explain what would result if- 1) this sodium atom gained a proton 2) this sodium atom gained a neutron 3) this sodium atom gained an electron (Yes, I know some of these results would not be stable in nature - the

1.Describe what happens to a carbon-11 atom when it undergoes
positron emission.
The decay of a carbon-11 atom _____(options;changes a nuetron
into proton, changes proton into neutron, is hit with a neutron,
reconfigures its protons and neutrons) and this causes it to
emit______(options; a negatively charged electron sized particle, a
positively charged electron sized partticle, two atoms and several
neutrons, two neutrons and two protons)

Post-lab Questions Part 2 8. Among the elements, hydrogen has the least massive atoms. An atom of hydrogen has an average mass of 1.66 x 10-24 g. This mass is very small, but remember it is only one atom which is composed of one proton and one electron! What is the relative mass of hydrogen if it is the least massive element? 9. How do the atomic masses found on the periodic table compare to the relative masses you calculated?...
