What would you like to do?
Actually chlorine and hydrogen will not share electrons; the chlorine atom steals the electron from the hydrogen atom, creating two separate oppositely charged ions.

Hydrogen atoms have one valence electron which is also the only electron they have.
the bond between the hydrogen atoms of hydrogen gas in which electrons are shared equally
What happens to each water molecule because of the unequal sharing of electrons by the two hydrogen atoms and the oxygen atom of a water molecule?
The water molecule becomes polar, with the oxygen end being very negative and the hydrogen end positive.
An atom is much more stable with 2 electrons in its first shell. Hydrogen has only 1 electron, so two atoms of hydrogen combine to form a H2 molecule, which enables each of th…em to share electrons. This allows them to behave as if they each had 2 electrons in the shell.
No the hydrogen and oxygen atoms do not equally share their electrons. The oxygen atom has a greater electronegativity than the hydrogen atom, which means that the oxygen …atom has a greater attraction for electrons than the hydrogen atom.
2 electrons- because hydrogen is a diatomic element.
They form covalent bonds.
They form an ionic bond
It becomes an ion.
Because calcium has 2 valence electrons, it needs to get rid of them to have a stable noble gas conformation. Chlorine atom has 7 VE and only needs to gain one electron to hav…e the noble gas conformation. Therefore one calcium will give one electron to two chlorine atoms, therefore resulting in an ionic bond.
Does the chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do?
Yes. The electronegativity of chlorine is more than that of hydrogen. As such, the electrons are closer towards chlorine than hydrogen in HCl.
hydrogen atoms share electrons when it forms covalent bonds
The hydrogen nucleus has a single proton. A neutral atom of hydrogen therefore requires just one electron to balance the charge.
What happens when a hydrogen atom with a charge of plus 1 comes in contact with a chlorine atom with a charge of-1?
HCl is formed.
They form an ionic bond
Although not strictly speaking an "exchange", typically when the electron interaction happens with a sodium and chlorine atom, it follows the "ionic bond" model, the highl…y electronegative chlorine atom will cause the sodium atom to 'donate' its single outer shell electron to the chlorine atom, acquire an overall negative charge, and attract the now positive sodium ion, and the two atoms thus become a sodium chloride molecule.
