Why mass number of are always whole number?
The main reason is that many elements exist in several isotopic forms. These are atoms with the same number of protons and electrons but different numbers of neutrons. Since the atomic mass is essentially based on the number of protons and neutrons in each atom, the element will exist in several forms with different masses. The atomic mass is the average of the masses of these isotopes, weighted together according to their abundance.
What is equal set from equivalent sets?
equal sets with exactly the same elements and number of elements.equivalent sets with numbers of elements
What does find the average mean in math?
The average of a set of numbers is the sum of the numbers in the set divided by the number of elements in the set.
What are the dodging numbers up to 1 100?
Dodging numbers are numbers which some young children miss out, by mistake, when they are learning to count. Different children will miss out different numbers.
How many elements are in the set whole numbers between 3 and 15?
12
Isotopes of uncharged elements have different numbers of?
Isotopes differ in the number of neutrons they possess.
Which isotopes of uncharged elements have different numbers?
Isotopes of uncharged elements have the same number of protons (which determines the element), but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon with different numbers of neutrons but the same number of protons.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
What do elements of isotopes have differently?
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
How are isotopes and elements different?
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Isotopes of elements?
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
How are isotopes different than naturally occurring elements?
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
Does an elements composition vary?
It can if isotopes are present. They can contain different numbers of neutrons in the nucleus.
Do Isotopes of uranium have different atomic numbers?
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
How the elements of isotopes are alike and how they are different?
Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
Two atoms of same elements with different masses?
