How does adding an atom affect the position of existing atoms or lone pairs?

2 answers:

Adding an atom will increase the repulsion between existing atoms and lone pairs. Added atom will result in bond pair-bond pair and bond pair-lone pair repulsion. The magnitude of the lone pair-bond pair repulsion is greater than the bond pair-bond pair repulsion. The added atom will change the electron geometry and bring about a distortion in the molecular geometry.

Answer: the addition of another atom changes the geometry of the molecule

Explanation:

Bond electron pairs and lone electron pairs always repel each other because electrons have the same charge (negative charge). Therefore, they tend to stay far away as possible. This gives the molecule a unique geometry. Then if we add another atom to this molecule, the geometry changes again to minimize the repulsion.

Further explanation:

In a molecule all the bond electron pairs and lone electron pairs repel each other because they have the same negative charge.

Therefore, these electron pairs tend to stay as far as possible, giving the molecule a unique geometry.

If we are going to add one more atom to this molecule, it means there comes another bond electron pair.

Then the existing bond and lone electron pairs tend to repel the new bond electron pair as well.

As a result, the geometry of the molecule changes in order to minimize the strain caused by repulsion.

A human zygote has 46 chromosomes. This number of chromosomes represents what in a human cell?

SOVA2 [1]

If the sperm carries a Y chromosome, it will result in a male. During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.

I have a block of gold and the density is 13.54g/ml If I cut the block in half what is the density of the smaller pieces of gold

Delvig [45]

Answer:

<u><em>Density is the same</em></u>

Explanation:

The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.

Ok heres what i know, one of the reasons why visible light will pass through glass but not through other materials is because the molecules in glass require more energy than average to push electrons from one level to another. Photons in visible light simply do not have enough energy. Only photons of light with shorter wavelengths, such as those that make up ultraviolet light, have the ability to change the electrons in glass. This is why ultraviolet light is unable to pass through glass. Lol im in 6th grade this is all i know ! :)
