This may be wrong, I'm not a expert in elements. But here's what I know:
A element's atom has a specific number of protons in the nucleus. If you change the number of protons, you change the element. Forgive me if I'm wrong, but I'm only in 5th grade.
well the atomic structures of different atoms vary, the varying differences is only of protons, neutrons, and electrons, which differentiate between atoms. the proton or the electron numbers are always different among different atoms, for example the proton number or the atomic number of hydrogen is 1 while the atomic number of helium is 2.
Atomic structure is the shape and arrangement of the sub-atomic particles in an atom with a dense and central positive nucleus surrounded by electrons in orbits.
A crystal structure is the shape, size, and arrangement of atoms, ions, molecules in a repeating or periodic array over large atomic distance.
The main difference between the atoms of different elements is their atomic number, or the number of protons in the nucleus. Each element has a unique number of protons.
Atoms of different elements differ in their number of protons, neutrons, and electrons.
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
39K has 20 neutrons and 41K has 22 neutrons.
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
Two isotopes of an element have the same atomic number (number of protons) but have different mass numbers (sum of protons and neutrons). This means that they will differ in the number of neutrons despite being the same element.
Two isotopes differ in the number of neutrons in the nucleus. For example, Carbon-14 has 8 neutrons differing from Carbon-12 which has 6 neutrons.
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
Yes - by the basic definition of an element; excepting only isotopes of an element, which differ slightly from each other in atomic structure, but not enough to affect the element's outwards physical and chemical properties.
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
The specific terms atoms and elements are related in The Atomic Number. The Element that an Atom belongs to is determined by the number of Protons that are contained within Its atomic nucleus. The varying number of neutrons [for any given number of protons] that are needed to keep the atomic nucleus held together is what results in the varying Atomic Weight when compared to the Atomic Number.
