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.
How do you get a mass number?
Add number of protons and neutrons.
Which numbers are added to give the nucleon number of an ion?
No need to add. Use the elemnts mass number, which is the number of protons plus the number of neutrons
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
If an atom 26 protons 26 electrons and 30 neutrons what is it's mass number?
It's Atomic Mass is 56 (and some change) because the majority of the mass comes from the protons and neutrons which equal about 1 amu (atomic mass unit) while the electrons equal a fraction of a percent so just add up the protons and electrons to get the atomic mass henceforth the mass number
What is the mass number of 26 protons and 30 neutrons?
The mass number is going to be 54. Mass number is found by adding the number of protons and the number of neutrons. The fact that there are 24 electrons, one for each proton, means the atom is neutral.
How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
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.
How to find the number of protons atomic number and the mass number with 12 as the number of electrons and 10 as the number of neutrons?
To find the number of protons (atomic number), you can use the number of electrons, in this case 12 electrons. Since atoms are electrically neutral, the number of protons is equal to the number of electrons, which is 12. To find the mass number, you add the number of protons and neutrons together. In this case, you have 12 protons and 10 neutrons, so the mass number would be 22.
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 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.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
