How many covalent bonds does oxygen form if each of its unpaired electrons participate in one bond?

2 answers:

8 0

The oxygen atom has 4 valence electrons. Valence electrons are the electrons found in the outermost shell of an atom. These are the electrons that participate in chemical reactions during bonding. Since 4 electrons make up 2 pairs, an oxygen atom is capable of making 2 covalent bonds.

Oxygen forms two covalent bonds or a single double bond.

Further explanation:

Oxygen forms two covalent bonds, or a double covalent bond. It has two unpaired electrons. Oxygen has six electrons in its outermost orbital which are involved in bonding.

Covalent bond:

A bond which is formed by the mutual sharing of electrons is called a covalent bond. The valence electrons of an atom are involved in the formation of a covalent bond. The covalent bond is of many types depending upon its kinds of bonding atoms or bond order. Oxygen atom containing six electrons in its outermost orbit forms a double covalent bond.

According to bond order the following are the three types of covalent bonds:

Single covalent bond:

The type of covalent bond which is formed by the mutual sharing of one electron pair is termed as single covalent bond.

For example:

The bond in hydrochloric acid is a covalent bond.

Double covalent bond:

A bond which is formed by the mutual sharing of two pairs of electrons is termed as double covalent bond.

For example:

Bond in carbon dioxide etc.

Triple covalent bond:

A bond which is formed by the mutual sharing of three pair of electrons is called a triple covalent bond.

For example:

Bond present in acetylene etc.

Strength of bonds:

Double covalent bond is stronger than a single covalent bond and a triple covalent bond is stronger than the double covalent bond.

Martian periodic table

denis23 [38]

Chemists considered Martian Periodic Table as one of the most useful tools they’ve used whose purpose is to arrange the Martian elements according to their properties and their atomic number. On this periodic table, it was found out that the properties seem to vary. Dmitri Mendeleev, the first to arrange the periodic table according to atomic mass in a manner that the elements with the same properties were grouped together. It was Henry Moseley who later arranged the periodic table in accord to the increasing number of atoms per element.

Write a balanced overall reaction from these unbalanced half-reactions. ln->ln3+ cd2+->cd

DochEvi [55]

Oxidation reaction
In ---> In³⁺ + 3e ---1)
reduction reaction
Cd²⁺ + 2e ---> Cd ---2)
when balancing the reactions, electrons have to be balanced. to balance the electrons multiple 1st reaction by 2 and 2nd reaction by 3
1) x 2
2) x 3
2In ---> 2In³⁺ + 6e
3Cd²⁺ + 6e ---> 3Cd
add the 2 equations to obtain the overall reaction

2In + 3Cd²⁺ ---> 2In³⁺ + 3Cd

I need HELP!!! Do the benefits of nuclear power outweigh the risks?

Georgia [21]

While there is no such thing as 100 percent safe, having nuclear energy is much safer than you think. It's thousands of times safer than conventional coal and other fossil-fuel-derived energy, not to mention the specter of environmental disaster from continued use of carbon-based energy sources.
