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.
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
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.
You think probable to isotopes; only the number of neutrons is different.
All atoms of the same element are the same.7) Isotopes are a family of atoms all of which have the same number of electrons, have the same number of protons in their atomic centers, but different numbers of neutrons.
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 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!!
Such atoms belong to a group in the periodic table of elements.
They are the same
yes. but only for a given isotope
shells
no
