Dot and cross diagram for oxygen ion

Chemistry
1 answer:
KatRina [158]3 years ago
4 0

Answer:

Explanation:

We can use dot and cross diagrams to show how a pair of electrons forms a covalent bond.

Here is the dot and cross diagram for oxygen (O2), a diatomic molecule. Notice the lone pairs of electrons and the two shared pairs of electrons.

There are different kinds of covalent bonds:

a single covalent bond is when two atoms share a single pair of electrons. Represented by a single line (–).

a double covalent bond is when two atoms share two pairs of electrons. Represented by a double line (=).

a triple covalent bond is when two atoms share three pairs of electrons. Represented by a triple line (≡).

Aleonysh [2.5K]

The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

The atmosphere has been divided into five layers based on the availability and the composition of different elements.

<h3>Troposphere</h3>

The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.

The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.

Pat measures a small rubber ball and then makes three other balls of the same diameter from lead, foam, and wood. Which ball has
natima [27]

Hey there!

Your answer is lead.

If they all have the same diameter, then the density is what is different.

Density is the amount of mass in an amount of space.

The material with the highest density, meaning there is more mass within that amount of space, is lead.

The more mass an object has, the more inertia it has.

So, since lead has the most mass, it also has the most inertia.

Hope this helps!
