When are substances isotopes?

Isotopes are atoms of the same element but having a different number of neutrons.


Are electrolytes isotopes?

Electrolytes are substances able to be dissociated in solution or after melting.Isotopes are atoms of chemical elements; isotopes have different number of neutrons.


What term would you use to classify the two substances of how their atomic mass and atomic number?

They are isotopes.


Which has more isotopes neon -10 or neon-12?

Neon has the atomic number 10 which means it has 10 protons, it cannot have 12. Different isotopes of an element have the same number of protons but a different number of neutrons. There are three stable isotopes of neon.


What is the name of a carbon isotopes that has a mass number of 12?

The isotope is named "carbon-12".


Two isotopes of the element rubidium differ in their number of protons?

no isotopes of a particular chemical element all have the same number of protons


Is the number of carbon 14 isotopes much greater than the number of carbon 12 isotopesin a normal sample of carbon?

No. The only mass numbers of carbon isotopes that occur naturally are 12 and 13, and the number of atoms with mass number 12 is much greater than the number of atoms with mass number 13 in any carbon from natural sources. Carbon-14 exists at all only in carbon including man-made isotopes.


Atoms of same chemical element that have different atomic mass are known as?

Isotopes. They differ in the number of neutrons in the nucleus.


How many neutrons are in a atom of magnesium?

Number of neutrons = Atomic weight - Atomic number (number of prtons) The atomic number of magnesium is 12; the standard atomic weight is circa 24,3. But magnesium has many isotopes (three are natural) and the number of neutrons is variable in the isotopes - from 7 to 28. The most common natural isotope, 24Mg, has 12 neutrons.


Atom of same element with different number of neutrons?

Isotopes have the same number of protons but different number of neutrons. Carbon has several isotopes: carbon-12, carbon-13, carbon-14, etc. They all have 6 protons but their mass and physical properties change due to the number of neutron.


What does the symbol of isotopes of the same element look like?

Isotopes have different masses, so the superscript preceding the symbol will be different. An example could be carbon with atomic mass 12 and carbon with atomic mass 14. 12C and 14C with the 12 and 14 being superscripts, identifies the different isotopes.


How many protons are there in the C-12 isotopes?

All isotopes of the same element differ only in the number of neutrons, not protons. As we are talking about carbon, all isotopes of carbon have 6 protons.There are 6 protons in C-12 isotope. Its atomic number is also 6.The number of neutrons is also 6.
