Is the number of electrons in an atom must equal the number of neutrons?
No. For an atom to be neutral (no charge, not an ion) the number of electrons must equal the number of protons. Usually the number of electrons is very close to the number of protons though.
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.
What number of particles in an atom usually equals the number of protons?
Unless it is an ion, the number of electrons will equal 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
