What do you know about an isotope?
Isotopes have same atomic number. They have different mass numbers. Their physical properties are different.
What is atomic charge no?
atomic charge
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What does band of stability for atomic nuclei refer to?
The band of stability contain stable isotopes.
Why inert gases occur in atomic form?
to get stability
What three factors effect the nuclear charge?
The stability of a nucleus depends on the ratio of protons to neutrons. It's not a simple ratio that's the same for all atomic numbers, it varies. For small atomic numbers, 1:1 is about right. For higher atomic numbers, more neutrons are needed.
How is the element with atomic number 82 in the periodic table different from the element in the atomic number 81?
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
A partical in the atomic nucleus that carries no charge?
The neutron is the particle in the atomic nucleus that carries no charge.
What is it called when the neutron's and protons are different?
Neutrons and protons both are located at the atomic nucleus. Protons carry +1 charge each. Neutrons carry no charge.
What does it mean if an element is radioacitive?
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
What do protons and neutrons equal?
It may or may not equal, neutrons are responsible for stability of nucleus.
Which atomic subparticle does not have a charge?
A neutron is neutral, meaning no charge.
