What else can I help you with?
What do two diffenent neutral isotopes of the same element have in common?
The number of protons per atom, and the number of electrons per atom.
What two isotopes cause the nucleus to split an atom bomb?
The isotopes are uranium-235 or plutonium-239.
How many electrons and isotopes are in a helium atom?
2 electrons. He-4 and He-3 are the two most occuring isotopes.
An atom of which element contains two neutrons?
Two isotopes have two neutrons: 3H and 4He.
Two atom of the same elements with different mass number was?
ISotopes
Two different isotopes of the same atom have what?
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
What do different isotopes of the same atom have?
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
Are they more than a single neutron in an atom?
yes (except for the two isotopes of hydrogen).
How many neutrons are in an atom he?
In total nine different isotopes of helium are known to exist. Helium 3 (one neutron) and helium 4 (two neutrons, by far the most common isotope) are the only stable isotopes. The other 7 isotopes (helium 2, 5, 6, 7, 8, 9, and 10) are unstable and rapidly decay into stable isotopes.
How many neutrons are in an atom with an atomic number of 3?
The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li. If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.
What do two neutral isotopes of the element have in common?
The same numbers of protons and of electrons; the difference between isotopes is in the number of neutrons.
Where does the 0.5 in chlorine's atomic mass come from?
There are different isotopes of the element. Isotopes are atoms of an element that have different amounts of protons, so the isotopes with more protons weigh more because there is more mass in the atom. Some isotopes are more common than others, and the atomic mass is a weighted AVERAGE of all the isotopes of that element. On most elements there is a large difference between the most common and lesser common isotopes, but chlorine has 2 isotopes that are very close. So the average ends up between the two numbers. The actual weight of 1 atom will never be something.5 because protons and neutrons weigh 1amu and electrons weigh 0. But in most cases the sample of a chemical you use will be a mixture of the isotopes, so the .5 weight will be correct.
