Draw the Lewis structure for H2O. How many lone pairs of electrons are there in the central atom?

2 lone pairs of electrons

Explanation:

In this case, the central atom is oxygen. If we check the periodic table we will have an atomic number of 8. So, the electronic configuration would be:

We have 6 electrons in the last level. Therefore, we have 6 valence electrons. For the hydrogens, we will have only 1 electron each. So, in total, we have 8 electrons.

With this in mind, we have to draw two lone pairs in the oxygen and 1 bond with each hydrogen.

See figure 1.

I hope it helps!

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

i think so it’s will be b yes i believe its
