Best answer: How many electrons does oxygen share with hydrogen?

Oxygen and hydrogen share one electron when they bond. By bonding with two hydrogen atoms, oxygen has its 6 outer shell electrons + 2 shared electrons from the hydrogen making 8 (and a filled shell makes a happy atom.

Does hydrogen and oxygen share electrons?

Two hydrogen atoms and one oxygen atoms are near each other. … Because there is both a strong enough attraction between atoms and room for electrons in the outer energy levels of the atoms, they share electrons. This forms a covalent bond.

How many electrons can oxygen share?

By sharing two pairs of valence electrons, each oxygen atom has a total of eight valence electrons. This fills its outer energy level, giving it the most stable arrangement of electrons.

How many electrons are shared with hydrogen?

Hydrogen, the only element in the first row besides Helium, fulfills the “octet rule” by sharing two electrons only. Two hydrogen atoms form a covalent bond to make a hydrogen molecule. Each contributes one electron and forms a system that is much more stable than the isolated atoms.

What does hydrogen and oxygen share?

Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge.

How many bonds does oxygen have?

To obtain an octet, these atoms form three covalent bonds, as in NH3 (ammonia). Oxygen and other atoms in group 6A (16) obtain an octet by forming two covalent bonds.

How Many Covalent Bonds Are Formed?

Atom (Group number) Number of Bonds Number of Lone Pairs
Oxygen (Group 16 or 6A) 2 2
Fluorine (Group 17 or 7A) 1 3

When hydrogen shares electrons with oxygen the outermost shell of the hydrogen atoms are full with?

By sharing electrons, each atom has electrons available to fill its sole or outer energy level. The hydrogen atoms each have a pair of shared electrons, so their first and only energy level is full. The oxygen atom has a total of eight valence electrons, so its outer energy level is full.

Why are oxygen and hydrogen happy sharing electrons?

Oxygen and hydrogen share one electron when they bond. By bonding with two hydrogen atoms, oxygen has its 6 outer shell electrons + 2 shared electrons from the hydrogen making 8 (and a filled shell makes a happy atom. … If oxygen bonds with 4 hydrogen atoms, it would have too many electrons to fit into its outer shell.

How many electrons does hydrogen bonding have?

Hydrogen is an exception to the octet rule. H forms only one bond because it needs only two electrons.

How many electrons does oxygen 15 have?

It has 8 protons, 7 neutrons, and 8 electrons. The total atomic mass is 15.0030654 amu. It has a half-life of 122.24 seconds. Oxygen-15 is synthesized through deuteron bombardment of nitrogen-14 using a cyclotron.

How many lone pairs does hydrogen have?

Hydrogen atoms have 1 bond and no lone pairs. Oxygen atoms usually have 2 bonds and 2 lone pairs.

How many stable electrons does oxygen have?

Oxygen has six valence electrons in its outer shell. Eight electrons are needed to fill the second level to achieve stability. So oxygen needs two more electrons to be stable.

When hydrogen is combined with oxygen what is produced answer?

When hydrogen combines with oxygen, it produces water and hydrogen peroxide.

How does H2 and O2 make H2O?

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

What is the ratio of the amount of oxygen in water to that in hydrogen peroxide?

The combining ratios of hydrogen and oxygen in water and hydrogen peroxide are 1:8 and 1:16.
