This very important characteristic is called the atomic weight. It represents a weighted average of the naturally occurring isotopes of an element. When a quantity of the element is weighed, the different isotopes - and the relative percentage they comprise of the whole - are accounted for. This makes for accurate readings in laboratory measurements.
(earth science voc. word "Atomic Mass")
Yes... it is called the mass number. Some call it the atomic mass or atomic weight but i believe atomic mass is the total count of the neutrons, protons and electrons in an atom. But the atomic mass usually refers to the count of neutrons and protons and the electrons being the decimal usually. although i suppose if there is enough electrons they could bring the mass up more than just making it a decimal...
The "atomic mass". If the mass is expressed in units of grams as is usual, the mass would be called "gram atomic mass." Sometimes, especially several decades or more ago, the value defined in the question was often called the "chemical atomic mass" of an element, which was contrasted with the "physical atomic mass" of a single isotope of the element.
It is the Atomic mass.
Yes but it is not really an average massbecause some isotopes are more common than others.
average atomic mass
The Atomic mass of that element.
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable
Element #105 is an artificial element, and it is called Dubnium.
transmutation - same as the alchemists called it.
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
They are called isotopes.
They are called isotopes.
Isotopes.
They are isotopes of that element, they have different neutron numbers.
Isotopes

yes, they are called isotopes
Isotopes
These atoms are called isotopes.
'ISOTOPES'. The definitive statement is ' Isotopes of the same element have a different number of neutrons'. NB Do NOT confuse with 'Allotropes' . Allotropes of the same element exhibit different physical characteristics. The elements Sulphur and Phosphorus are the two classic examples of allotropes.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
