What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Do isotopes of an element have the same atomic number?
They have the same number of protons (and electrons) - so proton number. They have a varying number of neutrons - Mass number. Proton number and Atomic number mean the same things, so Isotopes of an element have the same atomic number.
Has a mass about the same as a proton's?
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
How is mass number and atomic number the same?
They are not. Atomic number is the total number of protons in an atom. Mass number is the total number of protons and neutrons. The only isitope in which they are the same is Hydrogen-1 with 1 proton and no neutrons.
What is the formula for atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
How does beta radiation affect the nucleus?
The end result of beta- decay is that a neutron is converted into a proton, increasing the atomic number while keeping the atomic mass number the same. The end result of beta+ decay is that a proton is converted into a neutron, decreasing the atomic number while keeping the atomic mass number the same.
Is the mass of a proton the same as one atomic mass unit?
The mass of proton is only approx. equal to 1 amu.
What happen to atomic number and mass number of nucleus when it emits electron?
When a nucleus emits an electron, the atomic number increases by 1 since the nucleus gains a proton. However, the mass number remains the same because an electron is much lighter than a proton or neutron.
Can isotopes have he same atomic number?
Every atom of the same element will have the same atomic number. I.E. Hydrogen (H) will always have an atomic number of 1. However an atom can have different atomic masses due to different isotopes.
Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
