What is the bond between sodium and chlorine?

Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.
A.

What happens when you combine sodium and chlorine?

They combine as atoms, and separate as ions. When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. When this happens, the atom is called a positive ion.
B.

What does sodium and chlorine make when combined?

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

  • How does chlorine react with other elements?

    The reaction between chlorine and other elements can often be vigorous. For example, chlorine reacts explosively with hydrogen to form hydrogen chloride: Chlorine does not burn but, like oxygen, it helps other substances bum.
  • What is the balanced chemical equation for sodium chloride?

    In order to balance Na + Cl2 = NaCl you'll need to make sure the number of Na and Cl atoms are the same on both sides of the chemical equation. You do that by changing the coefficients (the numbers in front of atoms or compounds). First, be sure to count all of Na and Cl atoms on each side of the chemical equation.
C.

Why does the sodium atom lose an electron to chlorine?

The sodium atom and the chlorine atom want to make their outside shells contain only eight electrons. The sodium atom wants to lose an electron and the chlorine atom wants to gain an electron. When the two atoms come together the electron from the sodium atom jumps into the gap in the outer shell of the chlorine atom.
  • How many electrons does calcium want to lose?

    Calcium atoms will lose two electrons in order to achieve the noble gas configuration of argon. A neutral calcium atom has 20 electrons, while a calcium atom that has lost two electrons will have 18 electrons, and a neutral argon atom also has 18 electrons.
  • How many electrons does sodium have to gain or lose?

    It would need to gain 7 electrons to form an octet. Hydrogen and helium are the only 2 atoms that need 2 electrons in their outer shell to make it full.
    It would be much easier for the Na to lose an electron. It's oxidation number is +1.
  • How many electrons does beryllium need to gain or lose?

    So for the element of BERYLLIUM, you already know that the atomic number tells you the number of electrons. That means there are 4 electrons in a beryllium atom. Looking at the picture, you can see there are two electrons in shell one and two in shell two.
