What is the isotope iodine 75?
There is no such isotope (75) known. Iodine (atom number 53, average atomic mass 127) has 53 protons and 70 up till 82 neutrons. The lowest known isotope number therefor is 123.
What is the number of protons neutrons in radium?
What is proton number and neutrons number in isotope Fe 59?
All Iron (Fe) atoms have 26 protons. 59Fe has 26 protons and 33 neutrons. Since 26+33=59, it is known as 59Fe.
How many electrons neutrons and protons are in the nucleus of einsteinium?
Einsteinium has 153 neutrons, 99 protons, and 99 electrons. It's atomic mass is 252 and its shells are 2, 8, 18, 32, 29, 8, 2. Its chemical symbol is Es. Einsteinium has 19 isotopes; each isotope has a different number of neutrons.
How many protons in platinum?
depends on isotope.For the most common isotope Platinum-195 (33.5%), there are the following fermions:electrons = 78protons = 78neutrons = 117quarks (inside protons & neutrons) = 585Total = 858Also at any given moment there are an indeterminate number of bosons being interchanged between these 858 fermions to hold the atom together with the electromagnetic, weak, and strong forces:photons - electromagneticW & Z bosons - weakmesons - strong (between protons and neutrons)gluons - strong (between quarks)So even for an atom of one known isotope, the exact number of subatomic particles in it is unknown and cannot be known.
What is the isotope iodine 75?
There is no such isotope (75) known. Iodine (atom number 53, average atomic mass 127) has 53 protons and 70 up till 82 neutrons. The lowest known isotope number therefor is 123.
How many neutrons does iodine have?
The stable isotope of Iodine is 127 atomic weight and atomic number 53. So it has 53 protons and thus also 53 electrons (to balance the positive charge of the protons) . It has 127-53 = 74 neutrons.
What is the number of protons neutrons in radium?
How many protons and neutrons does radium have?
88
What are the number of neutrons protons and electrons in radium?
Atoms of the same elements that differ only in the number of neutrons are known as?
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
What is proton number and neutrons number in isotope Fe 59?
All Iron (Fe) atoms have 26 protons. 59Fe has 26 protons and 33 neutrons. Since 26+33=59, it is known as 59Fe.
How many protons electrons and neutrons dose americium have?
There are 19 known isotopes of americium, with neutron counts ranging from 136 to 154. Americium-241, the easiest to produce, has 146 neutrons. Number of neutrons = Atomic weight (rounded) of an americium isotope - 95 Each isotope has a different number of neutrons. Americium has also 95 protons and electrons.
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
Why doesn't the number of neutrons identify an element?
To completely specify the type of atom, you would have to know the element and the isotope - that is, the number of protons and the number of neutrons. If either of these is different, you have a different type of atom. Isotopes of different elements (i.e., different number of protons) may have the same number of neutrons: in total, 118 elements are known (the number of protons can go from 1-118), but over 3000 types of atoms or isotopes are known.
How many nuetrons does an einsteinium element have?
99 protons 99 electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.Einsteinium has 99 protons.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
