How many neutrons are in the nucleus of a atom?
Atomic nuclei are composed of protons and neutrons. The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element. There can be an average because, unlike proton number, neutron number can vary from isotope to isotope. For example, carbon can have 6 or 7 neutrons and still be stable, but it always has to have 6 protons, or else it'd be a different element. Because atomic mass is equal to the number of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from the total number of nucleons in a given isotope. To do this, subtract the atomic number from the atomic mass.
How hydrogen is stable without a neutron?
There is only 1 proton and that proton does not have to be bonded to any other protons.
How does an atom that loses electrons such as in beta decay end up with a different atomic number?
When the number of protons in the nucleus is changed, and an electron or positron created, the atom undergoing decay becomes, in effect, a different element. The number of protons is what determines the elemental status of an atom.In beta decay, a neutron becomes a proton and the nucleus releases an electron and antineutrino.In beta+ decay (aka positron emission), a proton becomes a neutron, releasing a positron and antineutrino. In each case, the decay changes the neutron/proton ratio and makes the atom more stable.
When iron 59 undergoes beta decay what is the results?
The daughter product in this nuclear process will be cobalt-59, which is stable. One neutron becomes a proton and an electron. The proton remains, adding 1 to the nuclide's atomic number; the electron is emitted as a beta particle.
A beta particle is a what created and emitted from an unstable nucleus?
A beta particle is an electron or a positron emitted from an unstable nucleus during beta decay. Beta decay occurs when a neutron in the nucleus changes into a proton and emits either an electron (beta minus decay) or a positron (beta plus decay) to achieve a more stable configuration.
How does Neutron emission from a nucleus affect an element?
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.

What is the mass number of deterium?
The mass number of deuterium is 2, as it contains one proton and one neutron in its nucleus. It is a stable isotope of hydrogen.
How do the isotopes hydrogen 1 and hydrogen 2 differ?
The basic difference is a neutron. Most hydrogen has a single proton for a nucleus. Hydrogen-2 has a neutron stuck to the proton, and hydrogen-3 has two neutrons stuck to the proton. Hydrogen-3 is a rare and highly unstable form of the first element.
A beta particle is a what created and emitted from an unstable nucleus?
A beta particle is an electron or a positron emitted from an unstable nucleus during beta decay. Beta decay occurs when a neutron in the nucleus changes into a proton and emits either an electron (beta minus decay) or a positron (beta plus decay) to achieve a more stable configuration.
If you add a proton neutron and electron to an atom explain why the atom would not be the same element?
BECAUSE ON ADDING ANYTHING (PROTON, NEUTRON OR ELECTRON) THE CHEMICAL PROPERTIES OF THE ATOM DOES NOT REMAIN THE SAME. 1. AS ON ADDING ELECTRON THE ATOM WILL BE IONIZED AND WILL BECOME MORE NEGATIVELY CHARGED AND THUS WILL REACT WITH DIFFERENT ELEMENT IN A DIFFERENT MANNER OR FORM DIFFERENT CHEMICAL FORMULAS. FOR EXAMPLE: C + O2 = CO2 BUT IF WE ADD 2 MORE ELECTRONS TO OXYGEN THE IT WILL FORM CO. 2. THE ATOMIC MASS OF A HYDROGEN ATOM IS 1 BECAUSE IT ONLY CONTAIN 1 PROTON (i.e. NO NEUTRON) BUT IF WE ADD I NEUTRON TO IT ITS ATOMIC MASS WILL BE 2 WHICH IS THE ATOMIC PASS OF A DIFFERENT ELEMENT DEUTRIUM AND THUS THE ELEMENT WILL NOT REMAIN THE SAME.(not sure of the spelling & grammar.) (ii)THE ATOMIC MASS OF URANIUM'S STABLE ISOTOPE IS 238. IF WE ADD A NEUTRON ITS ATOMIC MASS WILL BECOME 239 WHICH IS THE ATOMIC MASS OF POLONIUM AND THUS THE ELEMENT WILL NOT REMAIN SAME. 3. IF WE ADD PROTON TO AN ATOM ITS ATOMIC NUMBER WILL CHANGED AND THUS IT CHEMICAL PROPERTIES WILL ALSO BE CHANGED.
What is the mass number and atomic number of nitrogen?
Mass number: 14 Atomic/proton number: 7 If you look at the periodic table, the mass number is the top and the atomic number is the bottom number.
What Atomic Number represents?
The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
