WebFeb 25, 2024 · All atoms have about the same size irrespective of the number of electrons present in the atom. The radius of an atom is about 1-2 Å. The atoms of different elements might or might not exist independently. Atoms of elements like argon and helium can exist independently, but those of oxygen, nitrogen sulfur cannot. WebThe radius of an atom is governed by the number of layers of electrons around the nucleus the pull the outer electrons feel from the nucleus. Compare fluorine and chlorine: In each case, the outer electrons feel a net pull of 7+ from the nucleus. The positive charge on the nucleus is cut down by the negativeness of the inner electrons. エクセルグラフ横軸範囲変更
