What is the number of protons and neutrons in iodine-131?
A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons).
How many neutrons are there in iodine-131?
There are 78 neutrons in the nucleus of a single atom of iodine-131.
What is 131 on the periodic table?
Please visit the Tellurium element page for information specific to the chemical element of the periodic table.
What is the mass number of isotopes of iodine?
Mass numbers of typical isotopes of Iodine are 127.
What is the atomic mass of an atom?
The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.
How many electrons does neon have?
Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. The chemical symbol for Neon is Ne.
How many protons does nitrogen have?
Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. The chemical symbol for Nitrogen is N.
How many protons does helium have?
Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He.
What is the lightest element on the periodic table?
With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
What is the most abundant element in the Earth's crust?
Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below.
How many protons does iodine have?
Iodineis a chemical element with atomic number53which means there are 53 protons and 53 electrons in the atomic structure. The chemical symbolfor Iodine is I. Atomic Mass of Iodine. Atomic mass of Iodine is 126.90447 u.
What is the unit of mass?
The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.
What is the atomic mass of 12C?
For 12C the atomic mass is exactly 12u , since the atomic mass unit is defined from it. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u.
What is density in math?
Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V. In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.
Which is heavier, a proton or a neutron?
The neutron is slightly heavier than the proton. This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on 12C with equal numbers of protons and neutrons. The nuclear binding energy varies between nuclei.
