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.

∙ 11y agoNo. Different atoms of the same element can have different numbers of neutrons. They are called isotopes. The mass number of an isotope is the sum of protons and neutrons in the nucleus. Isotopes are identified by their mass numbers, for example, carbon-12 and carbon-14.

∙ 13y agoNo. Generally definition of an element refer to a group of atoms that have same number of protons and share same chemical properties and called isotopes of an element. Though weight of isotopes can differ representing difference in neutron number.

When all atoms are the same is a what?
Element.
Is an element's atoms are all the same or different?
same
What is it called when all the atoms are the same?
a element :)
What are all elements are mixtures of?
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
Is it true that the number of protons in an element is the same for all neutral atoms of that element?
nO
Do all of the atoms of the same element have the same number of neutrons?
Yes, all atoms of the same element have the same number of neutrons.
Why do all atoms of an element have the same chemical prperties?
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.
In any element all atoms are what?
All the atoms have the same number of protons (element type).
All Atoms Of An Element Are Exactly?
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
Are all atoms the same?
Isotopes are atoms of the same element with varying number of neutrons. Thus, not all atoms are the same.
When all atoms are the same is a what?
Element.
What are Atoms with the same number of protons are?
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
Is an element's atoms are all the same or different?
same
All atom of an element have the same?
All atoms of an element have the same atomic number.
What is it called when all the atoms are the same?
a element :)
What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
