What number of protons and neutrons must be contained in the nucleus to result in a neutral atom?
For a neutral atom, the number of protons (which determines the element) must be equal to the number of electrons. This means that the number of protons should be equal to the number of electrons for the atom to be neutral. Neutrons have no charge, so the number of neutrons does not affect the overall charge of the atom.
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
What must the atomic number also identify?
Atomic Number identifies the following:No. of protons (same as the atomic number)No. of electrons (mostly same as no. of protons)Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)
The atomic mass of an atom is 46 and it has 22 neutrons. How many electrons does it have?
46. That answer is incorrect. If the atom has 22 neutrons, then it must have 24 protons to make up the total mass of 46. A neutral atom always has the same number of electrons as protons so the correct answer is 24.
How many protons electrons and neutrons are in an atom with an atomic number of seventy nine and an atomic mass of one hundred ninety seven?
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
What number of protons and neutrons must be contained in the nucleus to result in a neutral atom?
For a neutral atom, the number of protons (which determines the element) must be equal to the number of electrons. This means that the number of protons should be equal to the number of electrons for the atom to be neutral. Neutrons have no charge, so the number of neutrons does not affect the overall charge of the atom.
Do neutrons always equal the number of elecrons?
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
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.
Why is the number of protons equal to the number of electrons in an atom?
To maintain the neutrality of an atom the number of neutrons must be equal to number of electrons; in ions this number is not equal.
What must be equal in a atom?
Protons and Neutrons
A neutral atom has the same number of protons as it does neutrons?
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
How can the number of protons electrons and neutrons be calculated when giving the mass number?
The atomic number must be known along with the mass number. Then the number of protons or electrons is the same as the atomic number, and the number of neutrons is the difference between the mass number and the atomic number.
If an element has 12 protons and 17 neutrons how many electrons must it have?
The number of electrons in a neutral atom is equal to the number of protons, so in this case, the element must have 12 electrons.
How many neutrons and electrons does an oxygen atom have?
Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.

Atomic Number identifies the following:No. of protons (same as the atomic number)No. of electrons (mostly same as no. of protons)Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)
How do you obtain the mass number of an atom?
in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!hope this helped!!! :)
