What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
How do the numbers of protons, number of neutrons, and the mass number related?
mass no. = no. of protons + no. of neutrons
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The sum of the protons and neutrons is the mass?
No. The mass also includes electrons.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What determines an atoms atomic mass?
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
How many protons neutrons and electrons does ion have?
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.

What is an element made up of?
An element is made from atoms. Atoms contain protons, neutrons and electrons. Protons and neutrons contain quarks and gluons.
The atomic mass is equal to the sum of?
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
How many protons neutrons and electrons make up atom of nitrogen-15?
7 protons 7 electrons 8 neutrons
