The reality that water has actually two hydrogens attached come a single oxygen is established by the variety of bonds the an oxygen atom can form. Together you might know, all atoms are consisted of of a small nucleus surrounding by "cloud" the electrons. While these electrons don"t orbit the nucleus prefer the planets orbit the sun, they execute tend come spend more time at specific distances from that main spot. These distances depend ~ above the energy of the electrons (how "fast" they"re travelling roughly the nucleus). The most energetic, so furthest away, electrons are referred to as "valence" electrons and these room the electrons that interact with other atoms. One oxygen atom has 6 valence electrons. As it turns out, that doesn"t price much power to include up come 8 electrons to one atom choose oxygen"s valence shell, but including a ninth electron will price a great of power (you"ll find out why if you examine chemistry/physics in college) so the oxygen atom has an are for two an ext electrons before they get very hard to add. The hydrogen atoms carry out these electrons as soon as water forms. Adding much more hydrogen on top of H2O would need those extra electron from hydrogen to occupy much greater energy levels than is typically available. If H4O were ever before to form, it would certainly spontaneously decompose into H2 + H2O since the power of one H2 molecule is much reduced than those extra 2 O-H bonds.Hope this helps!
The proton has a +1 charge, oxygen has -2. For this reason to do neutral molecule H2O you need 2x(+2) +1x(-2)=0
Atoms are comprised a nucleus, which consists of protons and neutrons, as well as electrons, which type shells approximately this nucleus. In each electron shell, there are various numbers the electrons. The very first shell can only fit two electrons, and the 2nd shell fits eight. Oxygen, number 8 in the regular table, has actually eight electrons, 2 in the first shell and also 6 in the second. Hydrogen only has actually one electron i beg your pardon is in the very first shell.
You are watching: How many shells does oxygen have
Oxygen and also hydrogen re-superstructure one electron once they bond. Through bonding with two hydrogen atoms, oxygen has actually its 6 external shell electron + 2 common electrons indigenous the hydrogen making 8 (and a fill shell makes a happy atom. Each of the hydrogen atoms has actually their 1 electron + 1 mutual electron to to fill their shell with 2 electrons.
If oxygen bonds v 4 hydrogen atoms, the would have too many electrons to fit into its outer shell.Hope the helps.
Oxygen needs two electron to fill its outermost electron shell. Hydrogen has one electron come play with. Therefore, one oxygen atom demands two hydrogens come bond come in bespeak to complete its shell.
Oxygen atom (O) try to discover 2 electron on various other atoms the the various other atoms will share through them. For this reason 2 hydrogen atom (H) each share their 1 electron with 1 oxygen atom. That renders 1 molecule the water, H2O.
different kinds of atoms shot to share various numbers of electrons with other atoms. Some kinds the atoms have electrons to share, and also other type of atoms are trying come find an ext electrons. So once 1 carbon atom (C) renders 1 molecule with hydrogen atoms, it requirements 4 hydrogen atoms, and the molecule is CH4, which is methane.

In the same way that you have actually two hands and generally have the right to hold two things, oxygen tends to donate bonding through two things due to the fact that of the energy of the electrons. However, depending on the conditions, oxygen have the right to bond to three hydrogens, i m sorry happens where there are numerous hydrogens (that is, miscellaneous is strong acidic).
