you cant add proton to an atom...u can only add electron....
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
The mass of a neutral atom is the sum of the protons and neutrons. If an atom has 31 electrons, it must also have 31 protons to maintain neutrality. Adding the 31 protons and 38 neutrons gives a total mass of 69 atomic mass units (amu).
Let's see, 1hydrogen, 2helium, 3lithium, 4beryllium, 5boron, 6carbon, 7nitrogen, 8oxygen. Eight protons in one atom of oxygen. Oxygen is diatomic, so there would be 16 protons in a typical oxygen "molecule."
When the atomic number increases, the number of protons in the nucleus also increases. Since atoms are electrically neutral, the number of electrons in the atom would also increase to match the number of protons, maintaining a balanced charge.
An unknown element contains 24 protons, 21 electrons,and has mass number 54
no, you add the protons and neutrons
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
In normal chemical reactions, electrons are easier to add or remove from an atom. Protons and neutrons are never added or removed in normal chemical reactions. Only nuclear reactions can change the numbers of protons and neutrons, such as radioactive decay. However, even then the protons and neutrons are not added or removed in the way that electrons are.
No. It's the only part of an atom that may leave or join an atom easily. Nuclear fusion and fission add or remove other particles like neutrons and protons.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
Mass number/Atomic Mass
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
"Complete atom" sounds like a neutral atom - same number of protons and electrons. If you add or remove some electrons, you will have a non-zero electric charge.
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
well when you add all the protons and electrons, it forms a neutral balance
In the nucleus of the atom, protons and neutrons therein each add 1 atomic mass unit.
The atomic mass is the sum of the number of protons and neutrons in an atom. In this case, the atomic mass would be 14 (protons) + 13 (neutrons) = 27.
