Why do elements form an ionic bond

Chemistry
1 answer:
Lelu [443]3 years ago
5 0

Answer:

An ionic bond is formed when a metallic element and a non-metallic element form a compound.

Explanation:

As you may know, each atom contains a set amount of electrons. For example, Hydrogen has one electron, helium has two electrons, lithium has three electrons and so on.

Electrons come in shells. The first shell can hold 2 elections at most, and each shell past this point can hold 8 electrons. When an atom has a filled outer shell, it is considered stable. (This so why the noble gases are unreactive- they have a full outer shell of electrons.)

This is why compounds can form- it is the chemical bonding of 2 or more chemical elements: take NaCl, sodium chloride, or SO2, sulphur dioxide.

You specifically asked about ionic bonds. Ionic bonds, as expressed above, form between a compound of a metallic and non metallic element.

Let's take sodium chloride as an example. Sodium has 1 electron in its outer shell and chlorine has 7. Both need a full outer shell to become stable. Because of this, the sodium atom loses its only electron in its outer shell to become a sodium ion and the chlorine atom gains the electron to become a chlorine ion as well. Because of this, both ions have a full outer shell, rendering them stable.

Now, because the sodium ion is short of one electron, it has more protons than electrons, resulting in it having a positive charge. The chlorine ion is the opposite, having a negative charge.

How is heavy water different from natural water
Sergeu [11.5K]

Answer:

Instead of normal protium atoms, heavy water consists of two deuterium atoms. Like normal water, heavy water is an odorless liquid at room temperature. Moreover, deuterium, tantamount to protium, is also a stable isotope. This ensures that heavy water is not radioactive

mars1129 [50]

Answer:

Compound A and compound B are constitutional isomers with molecular formula C3H7Cl.

When compound A is treated with sodium methoxide, a substitution reaction predominates. When compound B is treated with sodium methoxide, an elimination reaction predominates.

Explanation:

Constitutional isomers are the one which differs in the structural formula.

When compound A is treated with sodium methoxide, a substitution reaction predominates.

That means sodium methoxide is a strong base and a strong nucleophile.

But when it reacts with primary alkyl halides it forms a substitution product and when it reacts with secondary alkyl halide it forms mostly elimination product.

The reaction and the structures of A and B are shown below:
