Are isotopes atoms of the same element?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Is a pure element an isotope?
Isotopes of an element can be separated by physical methods such as diffusion and mass spectrometry. Also, the isotopes of some elements can be separated by chemical methods such as electrolysis. Each isotope of an element is a pure substance.
What is isotopes of the same element?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.
What is composed of atoms of the same element?
Isotopes are atoms of the same element that contain an identical number of protons, but a different number of neutrons. Despite having different numbers of neutrons, isotopes of the same element have very similar physical properties.
What does it mean for an element to be pure?
pure substance
An element is a pure substance as it cannot be broken down or transformed into a new substance even by using some physical or chemical means. Elements are mostly metals, non-metals or metalloids. Compounds, on the other hand, are also pure substances when two or more elements are combined chemically in a fixed ratio.
Is an element pure substance?
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
Why do atoms have different isotopes?
Neutrons exist to stabilize the nucleus – without them, the nucleus would consist of nothing but positively-charged protons in close proximity to one another. Because there are different ways of stabilizing the protons, there are different isotopes.
Why atoms of the same element are the same?
Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element. An element with different isotopes occurs in nature.
Are all atoms the same in an element?
Atoms. each element is made up of identical particles of matter called atoms. all the atoms in a pure substance or element are identical to one another but different to the atoms in a different element.
What is the difference between an isotope and an atomic number?
Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number.
What do atoms have in common with each other?
The atoms have the same number of electrons and different numbers of protons. The atoms have different numbers of neutrons and the same number of protons. The atoms have different numbers of protons and the same number of neutrons.
Which of the following elements has the fewest number of isotopes?
Hydrogen has the fewest number of isotopes with only three. The elements with the most isotopes are cesium and xenon with 36 known isotopes. Some isotopes are stable and some are unstable.
What is the difference between tritium ion and isotope?
Yet tritium is unstable and radioactive while the other two isotopes are stable and non-radioactive. Ions are atoms which have a missing electron or an extra one. This is what gives the ion its positive or negative electrical charge. Isotopes are atoms which contain a different number of neutrons.
