How valence electrons are arranged in a lewis dot diagram?
choli [55]

Explanation:

In a Lewis dot diagram, the electrons are arranged so that, when full, two electrons placed beside each other are on four sides of the element symbol.

An electron is 3-dimensional, so you can start on any side on a 2D diagram.

Continue this pattern depending on how many electrons you have:

When adding an electron after the first, it is placed on the next side going either counterclockwise or clockwise. Which ever direction you choose, be consistent.

After the fourth electron, so that one electron is on each side, place a dot beside your first electron and continue the pattern.

The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below.
Diano4ka-milaya [45]

Answer:

There is one nitrate ion in the products, and two in the reactants of this equation.

Explanation:

1: We know a nitrate ion has the formula NO_{3}^{- , so we just need to count how many of them are on each side of the equation.

2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section (NO_{3} )_{2} , which shows that there are two nitrate ions in the reactant side (as seen by the little 2).

3: To find how many are on the products side, you do the same thing - this time there is only one NO_{3}^{- in the lithium nitrate.

So, there is one nitrate ion in the products, and two in the reactants of this equation.
