Native element minerals
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.
This is a single displacement reaction.
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
There is one element, oxygen, in ozone. Each molecule of ozone contains three atoms of oxygen.
it is an element as it contains same kind of atoms
For example graphite.
Boron is an element and therefore contains boron atoms.
All atoms of any single element have the same number of protons and electrons.
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.
This is a single displacement reaction.
I know it would be DaltonWho discovered that atoms are made of a single material formed into different shapes and sizes? that would be Dalton
Magnesium atoms have 12 electrons.

Rutherfordium is a single chemical element.
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
There is one element, oxygen, in ozone. Each molecule of ozone contains three atoms of oxygen.
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.
