In the nucleus there are two main subatomic particles: The protons and the neutrons. The number of protons in the nucleus determines the element the atom is: 1 proton = hydrogen , 99 protons = Einsteinium , 6 protons = carbon etc.
The number of neutrons in the nucleus varies from atom to atom, even atoms of the same element. This causes the mass of the nucleus to vary slightly and can effect properties such as stability or type of nuclear decay. Atoms of the same element with different masses are called isotopes. They differ by the number of neutrons with the proton in te nucleus:
1 proton + 0 neutrons = 1 particle in the nucleus = hydrogen
1 proton + 1 neutron = 2 particles in the nucleus = deuterium
1 proton + 2 neutrons = 3 particles in the nucleus = tritium

Answer: Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)
Once you add detergent (base) to water (H2O), you are breaking the surface tension.
Answer:
Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
Explanation:
The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23.
Sodium (Na) square from the periodic table. The mass number (23) is top-left. The atomic number (11) is bottom-left.
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
