More or less. Elemental atoms all have the same number of protons (and therefore also electrons); but they might vary in the number of neutrons. These variations are called isotopes of an element.
Elemental isotopes can make an atom heavier or lighter; it can even turn it radioactive. Examples include deuterium (heavy hydrogen) and radioactive carbon-14, used for dating fossils and man-made artifacts.
no,an element is composed of atoms of same kind.but a compound is made up of different kinds of atoms
Many elements contain isotopes, atoms having a different number of neutrons.
An element is made up of 1 atom.
Yes, it is.
no
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
Matter that is not a mixture of different types of Atoms. A pure substance is a collection of Matter that is comprised from [and or composed of] Atoms of only One Atomic Element.
- A molecule may contain different types of atoms.- An element can be composed from different isotopes.
Yes, an element is made up of atoms of the same kind. For example Gold (Au) is an element and is only made up of other Gold atoms. If there is more than one type of atom (calcium carbonate for example) it is considered to be a compound.
A pure element contains one sort of atoms, and all the elements have the same number of protons (which define the element). But the atoms can have different masses, so called "isotopes" (see link). Thus, chemically there is only one kind of atoms in a pure element, but there can be several physically different kinds of nuclei in a pure element.
No an element is composed of 1 type of atom but a compound is composed of 1 or more atoms
An element is composed of only one type of atom. Compounds are composed of different types of atoms (different elements) that are chemically combined.
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.

Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
No.
An element is a substance that is composed of atoms that are all of one type. Every atom, in turn, consists of at least two types of particles, protons and electrons. All of the atoms in a sample of an element have the same number of protons in them. It's a lot more complicated than this but this is a good start.
organelle
A compound is composed of different kinds of atoms that are covalently bonded together. Compounds are made up from atoms of different elements.
what is an atom of the same element with different mass numbers
Yes, an element is made up of atoms of the same kind. For example Gold (Au) is an element and is only made up of other Gold atoms. If there is more than one type of atom (calcium carbonate for example) it is considered to be a compound.
