How many isotopes of hydrogen are know?
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.
How many neutrons are in ni?
It depends on the isotope. The most common naturally occurring isotope is 58Ni. Ni has the atomic number 28, so there are 30 neutrons in that isotope. There are four other stable naturally occurring isotopes with atomic weight 60, 61, 62 and 64. There are also around twenty unstable and radio-isotopes with atomic weights ranging from 48 to 78.
A certain element has only two naturally occurring isotopes one with 18 neutrons and the other with 20 neutrons. The element forms 1- charged ions when in ionic compounds. Predict the identity of the?

What element has 7 neutrons and 3 electrons?
This will be an atom with 3 protons, so it has atomnumber 3, which is one of the Lithium isotopes, having 7 neutrons (Li-10, 92%). The other naturally occurring isotope (8%)is Li-9.
How many neutrons does platinium have?
Platinum has 6 naturally occurring isotopes, all of which have 78 protons. The number of neutrons can vary, but the most common isotopes have between 116 and 118 neutrons. The full list of isotopes is:190Pt (78 protons and 112 neutrons)192Pt (78 protons and 114 neutrons)194Pt (78 protons and 116 neutrons) about 1/3 of all platinum195Pt (78 protons and 117 neutrons) about 1/3 of all platinum196Pt (78 protons and 118 neutrons) about 1/4 of all platinum198Pt (78 protons and 120 neutrons) about 1/14 of all platinum
How are isotopes different than naturally occurring elements?
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
How can iodine z equals 53 have a higher atomic number yet lower atomic mass than tellurium z equals 52?
Because the naturally occurring isotopes of tellurium have fewer neutrons than the naturally occurring isotopes of iodine.
How may neutrons in Aluminium?
Aluminium has roughly a couple dozen isotopes; but the only one both stable and naturally occurring has 14 neutrons (mass number of 27).
How many isotopes of hydrogen are know?
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.
How many nuetrons are in a phoshorus atom?
That depends on which isotope you're after: Natural occurring Phosphor has 16 neutrons next to its 15 protons in nucleus, but also with 15, 17,and 18 neutrons are possible isotopes, though not stable and not naturally occurring.
How many neutrons are in ni?
It depends on the isotope. The most common naturally occurring isotope is 58Ni. Ni has the atomic number 28, so there are 30 neutrons in that isotope. There are four other stable naturally occurring isotopes with atomic weight 60, 61, 62 and 64. There are also around twenty unstable and radio-isotopes with atomic weights ranging from 48 to 78.
How has the amount of earths radioactive isotope changed over time?
Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
How many neutrons does a positively charged atom of calcium have?
Most naturally occurring calcium atoms have 20 neutrons, but they may also have 21, 22, 23, 24, 26, or 28. Isotopes with 21, 26, or 28 neutrons are radioactive. The isotopes with 21 neutrons are formed from isotopes with 20 neutrons which underwent neutron activation. Whether a calcium atom is positively charged or neutral does not affect how many neutrons it has.

Are there isotopes in nitrogen?
Nitrogen has 3 isotopes. All of them have 7 protons. (That's why they're nitrogen.) Let's look at the isotopes. 13N - Nitrogen with 6 neutrons 14N - Nitrogen with 7 neutrons 15N - Nitrogen with 8 neutrons The first isotope is a synthetic one. It must be made through a nuclear process. The other two are naturally occurring isotopes. A link is provided to Wikipedia, which was the source for this information.

Does Hydrogen atom have neutrons Does it have isotopes It used to have 3 isotopes but now recent chemistry Syllabus says it doesn't have neutrons?
There are three naturally occurring isotopes of hydrogen. The most common isotope, hydrogen-1, has no neutrons. It accounts for 99.99% of all hydrogen. Hydrogen-2 has a single neutron and accounts for most of the remaining .01%. Hydrogen-3 with two neutrons only exists in trace amounts.
What is the difference between an isotope and an atom?
An atom is the smallest possible particle of a chemical element consisting pr protons, electrons and (usually) neutrons. An isotope is one variant of an element with a given number of neutrons. Different isotopes of an element have different numbers of neutrons.
