Carbon has 4 valence electrons, oxygen has 6

Aliun [14]2 years ago

4 0

Answer:

Carbon has 4 valence electrons

Explanation:

The valence electrons are those found in the last energy level of the atom.

They are responsible for the interaction between atoms,

they can form bonds.

Let's see the electronic configuration of carbon.

The atomic number of C is 6 (Z=6)

$C= 1S^2 2S^2 2P^2$

To know the number of valence electrons that we have we count in the last energy level of the atom.

The last energy level of carbon is 2 and we 4 electrons is this level.

So carbon has 4 valence electrons.

What is the easiest way to explain molecular compounds and covalent bonds also adding information about valance electrons?

wlad13 [49]

Answer:

Molecular compounds consist of two or more nonmetals. The nonmetals that make up a molecular compound are held together by covalent/molecular bonds. Covalent bonds is known as the "sharing" of valence electrons between two or more chemical species. Valence electrons are shared so that the atoms of the compound can become stable, much like how ionic bonds transfer valence electrons between atoms to achieve stability.

Why is Hawaii made of volcanoes?

Vadim26 [7]

Answer:

Explanation:

The Hawaiian Islands were literally created from lots of volcanoes—they're a trail of volcanic eruptions. In the case of the Hawaiian Islands, the Pacific Plate is continually moving to the northwest over the Hawaiian hot spot. This movement caused the Hawaiian chain of islands to form.

Determine the formula of chromic acid.

Katyanochek1 [597]

Answer: The formula of chromic acid is $H_2CrO_4$

Explanation:

We are given an ionic compound named as chromic acid. This acid is formed by the combination of hydrogen ion and chromate ion.

An acid is defined as the substance which releases hydrogen ion when dissolved in water.

Hydrogen is the 1st element of periodic table having electronic configuration of $1s^1$ .

This element will loose 1 electron to form $H^{+}$ ion.

Chromate ion is a polyatomic ion having chemical formula of $CrO_4^{2-}$

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is $H_2CrO_4$

Thus, the formula of chromic acid is $H_2CrO_4$
