Put simply, a substance that has all the same atoms in, is classified as an element.
All hydrogen atoms are the same but they are different from the atoms of other elements.
1) elements are composed of atoms 2) atoms of same elements = 3) atoms of different elements not = 4) atoms fomr compounds in definite ratios H2O
All atoms are elements. Single (or even a "few") atoms do not have the properties of large masses of atoms.
number of valence electron
Yes, atoms make up almost everything, they can only be broken down into protons, neutrons and electrons. An element is a substance found on the periodic table with certain rules and regulations given to each element. An element is made up only of atoms. A compound is a mixture of two or more elements that can be broken down into elements again, it is not a pure substance as such. So a compound is made up of elements, elements are made of atoms.
The answer is : no.
Elements are made of atoms. Each element is made up of the same kind of atoms, having the same atomic number.
Isotopes are atoms of the same elements with different number of neutrons.
Atoms of different elements have no specific relationship but if they have same no of neutrons then they are isotones, if they have same mass no then they are isobars, atomic no of two elements can neither be same.
All hydrogen atoms are the same but they are different from the atoms of other elements.
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
no
Elements.
They are the same by their fillings. Atoms in elements have fillings just like pies!!
Elements are the building blocks of matter. All atoms of the same element have the same atomic number. The mass number of atoms of the same element can vary.
Such atoms belong to a group in the periodic table of elements.
They are the same
