are all atoms of the same size?

As you add more protons and neutrons, the mass increases. ... On the other hand, if you are speaking of size, then atoms are all about the same size whether it's a hydrogen atom (the simplest and least massive with one proton and one electron) or a lead atom (with 82 protons, 82 electrons and 125 neutrons).

Atoms cannot be created nor destroyed, and they are indestructible; they cannot be broken into smaller parts. ... All atoms of an element are identical, in both mass and properties. Atoms of different elements have different mass and properties.

The number of protons in the nucleus of every atom of an element is always the same, but this is not the case with the number of neutrons. Atoms of the same element can have a different number of neutrons. ... These atoms are called isotopes, which are atoms of the same element that have a different number of neutrons.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
542564
The element of an atom is decided by the number of protons (which is the same as the number of electrons) in the atom. ... Atoms of the same element can differ in their mass which is the case if the number of neutrons in the atoms is not the same. These atoms with different mass are called isotopes.

Atoms of the same element must have the same number of protons , but they can have different numbers of neutrons . Atoms of the same element with different numbers of neutrons are called isotopes .
354833
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).

Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six.

Identical Protons, Different Elements All protons are identical. ... In fact, atoms of any given element have a unique number of protons that is different from the numbers of protons of all other elements. For example, a hydrogen atom has just one proton, whereas a helium atom has two protons.

Atoms of the same element can have different numbers of neutrons, however. Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes.

In reality, atoms do not contain any empty space. Rather, they are filled completely with spread-out electrons, making the shrinking of atoms impossible.
762336
Atoms are made up of smaller and even smaller particles of matter. However, those smaller particles don't have the properties of an element. The electrons in a gold (Au) atom are the same as the electrons in an atom of neon (Ne).
1091276
The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
1066726
Atoms of the same element always have the same number of protons ( is it had a different number of protons it would be a different element). However atoms of the same element can have different numbers of neutrons (this gives them a different mass number). Different versions of the same element are called isotopes.

Arranging the atoms It is fairly easy to arrange the atoms according to atomic size. We know that atomic size increases from right to left and from top to bottom in the Periodic Table. The smallest atoms are at the top right and the largest atoms are at the lower left of the Periodic Table.
293655
Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass number (like that for isotopes) . Different mass number will have different number of neutrons.

All the atoms of an element have the same properties (assuming they are the same isotope). Some examples are iron, magnesium, gold, etc. Compounds are composed of two or more elements in a fixed ratio.
