Number of protons.
They do not. All atoms of an element have the same number of protons otherwise they would not be that element. Taking carbon as an example, most carbon has 6 neutrons and is known as Carbon-12. There are traces of Carbon-13 with 7 neutrons and even traces of Carbon-14 with 8 neutrons present. So all the atoms in a lump of carbon would not have the same number of neutrons.
Two atoms are from the same element if they have the same number of protons in their nuclei. This is the defining characteristic that determines an element's identity. For example, all carbon atoms have 6 protons, so any two atoms with 6 protons are considered to be the same element, carbon.
When all atoms are the same, it forms a chemical element. Each element is characterized by a unique number of protons in its nucleus, which determines its chemical properties. Examples of elements include oxygen, carbon, and hydrogen.
An element is composed of atoms that have the same number of protons in their nucleus. This means that all atoms of a particular element have the same atomic number, defining the element's unique identity based on the number of protons. For example, all atoms of carbon have 6 protons in their nucleus, making them the same type of atom.
Yes, all atoms of the same element have the same number of neutrons.
Yes, all atoms with the same number of protons belong to the same element. The number of protons in an atom determines its atomic number, which defines the element. For example, all atoms with 6 protons are carbon atoms, regardless of the number of neutrons or electrons they have.
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
If it is a pure element, yes usually but not always. If it is a mix of isotopes then no. Carbon for example is not pure C12 - with 6 protons and 6 neutrons. Naturally there is some C13 and traces of C14 with 7 and 8 neutrons respectively present.
All the atoms have the same number of protons (element type).
The substance in which one or more atoms have the same number of protons is called an element. Each element is defined by its unique number of protons, known as the atomic number. For example, all carbon atoms have six protons, categorizing them as carbon. Elements can exist as single atoms or as molecules consisting of two or more atoms of the same or different elements.
Yes, all carbon atoms have the same atomic number, and that is 6.
Isotopes are atoms of the same element with varying number of neutrons. Thus, not all atoms are the same.
