What two particles of the atom are added together to get the atomic mass?
4
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
Why the magnesium have a atomic mass of 24?
Magnesium has 12 protons and 12 neutrons in its nucleus. The atomic mass is the number of protons and the number on neutrons added together, so 12 + 12 + 24.
What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
What is an example of atomic mass?
The Atomic Mass is the number of electrons and protons and neutrons added together.
What two particles of the atom are added together to get the atomic mass?
4
What are the formula weight of NaCl and BaCl2?
The molecular weight of NaCl is 58.44g/mol, the atomic mass of Na is 22.99 and the atomic mass of Cl is 35.45 when added together we get 58.44 g/mol.The molecular weight of BaCl2 is 208.233g/mol, the atomic mass of Ba is 137.327 and the atomic mass of Cl2 is (35.453)(2) = 70.906 when added together we get 208.233g/mol
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
What is the number of protons and neutrons added together in a nucleus?
The number of protons and neutrons added together gives the atomic mass number, nucleon number or often simply the mass number". This is DIFFERENT from the (relative) atomic mass, once called atomic weight, which is the average mass of the naturally occurring isotopes of an element in a sample relative to 1/12 th mass of carbon-12.
What two subatomic particles are added together to calulate the atomic mass?
Protons, neutrons and electrons.
The mass of all particles of an atom added together is its what?
The sum of protons and neutrons in an atom is called mass number.
Why the magnesium have a atomic mass of 24?
Magnesium has 12 protons and 12 neutrons in its nucleus. The atomic mass is the number of protons and the number on neutrons added together, so 12 + 12 + 24.

How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
What number does the number of protons plus the number of neutrons give you?
The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
