What else can I help you with?
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
What is the mass of a neutral atom with 31 electrons and 38 neutrons?
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).
What element do you get if you add two protons to an oxygen atom?
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."
What happens to the number of electrons in an atom when the atomic number increases?
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.
What happens when you increase or decrease the number of electrons in an atom?
if electrons are added to a neutral atom then it changes to a negatively charged ion (anion) and on the other hand if electrons are removed then the atom changes to positively charged ion (cation)
Do you have to add the protons and electrons in order to find the atomic mass of an atom?
no, you add the protons and neutrons
What is the number of an atom with 5 protons and 7 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.
What particles are easier to add to and remove from an atom?
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.
Is An electron is the only part of an atom that may leave or join an atom?
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.
How would you figure the number of protons or electrons in an atom?
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.
The protons and neutrons in an atom add up to give the atom's?
Mass number/Atomic Mass
What two subatomic particles do you add together to get the mass number?
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.
What charge positive negative or neutral does the complete atom have?
"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.
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
How do the parts of the atom cause the atom to be neutral?
well when you add all the protons and electrons, it forms a neutral balance
What is the Mass of an atom is located in what structure of the atom?
In the nucleus of the atom, protons and neutrons therein each add 1 atomic mass unit.
An atom has 14 protons and 13 neutrons what it its atomic mass?
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.
