what is the difference between elements and isotopes in terms of composition?

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. ... All isotopes of a particular element have the same number of protons, but can have different numbers of neutrons.

Isotopes are atoms of an element with the normal number of protons and electrons , but different numbers of neutrons. Isotopes have the same atomic number, but different mass numbers.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

Isotopes have a same number of electrons and protons in all atoms. A . B . Isotopes : They are the atoms of a given element which have the same atomic number (Z) but different mass number (A) i.e. They have same Nuclear charge (Z) but different number of Neutrons (AZ).

Protons carry a positive charge and electrons carry a negative charge. ... The isotope of an element still has the same number of protons, so it has the same atomic number. Isotopes also have the same number of electrons. The main difference between isotopes of the same element is that they different numbers of neutrons.

Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).

The single most important difference between these elements is the number of protons each one contains in its nucleus. The number of protons an atom contains dictates how many electrons it will have. It is the arrangement of electrons around an atom's nucleus that determines that atom's chemical properties.

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. ... A compound is a substance made from two or more different elements that have been chemically joined.

Explanation: Isotopes of an element are atoms of the same element with same number of protons but different number of neutrons.

Different isotopes of an element have different mass numbers, but react chemically in exactly the same way. The relative atomic mass of an element is the average mass of the isotopes in a naturally occurring sample of the element, taking into account the proportion of each isotope present.

The atomic number is defined by the number of protons in an element. An element is defined by the number of protons the nucleus contains and doesn't have anything to do with how many isotopes the element has.

The number of protons determines an element's atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess.
428320
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. ... Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass.
852535
Atoms of the same element can differ in their mass which is the case if the number of neutrons in the atoms is not the same. These atoms with different mass are called isotopes.

No. Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.
566119
Elements are composed of only 1 type of atoms and any subdivision can only result in same element. All the atoms of an element have the same properties (assuming they are the same isotope). Some examples are iron, magnesium, gold, etc. Compounds are composed of two or more elements in a fixed ratio.
