The number of neutrons in an atom can vary....ie an elements can exist with atoms that have the same number of electrons (and so are chemically the same) but have a different number of neutrons. These are called isotopes.

∙ 13y agoThey are not equal. To work this out you will need to look at a Periodic Table (or to know the atomic number and the mass number). Minus the atomic number from the mass number to give your answer. (the atomic number is the number above an element square in the periodic table and the mass number is the number below)

In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
Atomic number equals the number of?
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
The number of these is equal to the number of electrons in an atom?
A neutral atom has equal numbers of elecrons and protons.
Are protons and electrons always equal?
yes,,,because the number of protons is equal to the number of electrons. No, when electons are lost or gained by an atom (number of protons stays the same) the atoms become 'ions,' which are positively or negatively charged respectively.
Is the number of valence electrons equal to the number of protons?
No, the number of total electrons is equal to the number of protons.
Do protons and electrons have the same number?
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
Is the number of protons no of electrons?
Yes , the no. of electrons is equal to the no. of protons
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
When atoms are at rest what do they have an equal number of?
protons and electrons protons and electrons
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
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.
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What is a number of protons also number of electrons in an element?
Yes, they are equal. Every atom will have an equal amount of protons and electrons.
Does the number of electrons in an atom give its atomic number?
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
