![]() Oxygen and hydrogen atoms are non-metallic atoms. The electron configuration of oxygen shows that the valence electrons of oxygen are six. Since the last shell of a hydrogen atom has an electron, it can easily form bonds with other elements by sharing electrons. Therefore, the valency of hydrogen ions is 1. On the other hand, hydrogen donates an electron to form a bond or compound. Therefore, the valence electron of a hydrogen ion is zero. Since the hydrogen atom has only an electron, hydrogen can easily leave the electron and turn into a positive ion.Īfter the hydrogen atom donates electrons, the last shell of hydrogen has no electrons. Those atoms that donate electrons and turn into positive ions are called cations. How many valence electrons does hydrogen ion(H +) have?Įlements that have 1, 2, or 3 electrons in their last orbit can easily turn into positive ions by donating electrons. Having an electron, hydrogen can easily leave or share an electron. Valency and valence electrons of hydrogenĪtoms receive, leave, or share electrons during the formation of compounds or bonds. The valence electrons determine the properties of the element and participate in the formation of bonds. The total number of electrons in the last shell after the electron configuration of hydrogen is called the valence electrons of hydrogen. The valence electrons are the total number of electrons in the last orbit(shell). What are the valence electrons of hydrogen? Therefore, the number of neutrons in hydrogen is 0. We know that the atomic number of hydrogen is 1 and the atomic mass number is about 1(1.0080u). That is, neutron number (n) = atomic mass number (A) – atomic number (Z) The number of neutrons in an element is obtained from the difference between the number of atomic masses and the number of atoms. That is, the hydrogen atom has a total of an electron. Electrons equal to protons are located in a circular shell(orbit) outside the nucleus. ![]() That is, the number of protons in the hydrogen is 1. The atomic number is the number of protons. Protons and neutrons are located in the nucleus. The nucleus is located in the center of the atom.
