Answer: increases

Explanation:

The elements in the periodic table are arranged in order of increasing atomic numbers. The horizontal rows are called as periods and vertical columns are called as groups.  

The elements in the groups are arranged in order of increasing atomic numbers and thus the electrons are being added.The electrons are added to new energy shells.

But the effect of addition of new shells outweighs the increase of nuclear charge and thus the atomic radius of the atoms will keep on increasing as we move down a column in the periodic table.

Tomic radius INCREASES as you go DOWN a Group because each successive Period (row) has an additional occupied energy level. you can think of it this way: each time you drop down a row, you add a "ring."

An atom emits of wavelength 1.08 meters. what is the energy change occurring in the Atom due to this emission? (Planck’s constan
butalik [34]

To answer this question, we can use the following equation:

e=\frac{h*c}{lambda}

where e is the energy change, h is Planck's constant, c is the speed of light (m/s), and lambda is wavelength in meters. So then we can plug in the information:

e=\frac{(6.626x10^{-34}J*s)(2.998x10^{8}\frac{m}{s})}{1.08m}

e=\frac{1.9865x10^{-25}J}{1.08}

e=1.84x10^{-25}J

So the energy that is omitted by the atom is 1.84x10^{-25}J.

Why is the reaction SO2 + H2O → H2SO2 not balanced?
aalyn [17]

There are more oxygen atoms in the reactants while there are less oxygen atoms in the product.

Both sides of the equation is supposed to be balanced for a balanced equation. If any one of them isn't balanced, the equation remains unbalanced.

The main reason why the reaction above can not be balanced is:

This chemical reaction SO2 + H2O -> H2SO2 is not correctly written.

It must be: SO2 + H2O -> H2SO3

Water is a polar molecule, meaning the electrons that are shared between the atoms aren't shared equally so oxygen attracts more
amm1812

Answer:

Magnet with a positive and a negative pole

Explanation:

A great analogy to demonstrate what a polar molecule looks like is to imagine a magnet. A magnet has one positively charged end and one negatively charged end, two poles, that is.

Imagine that we have a magnet of a shape of a prism (water molecule has a bent shape). The two base vertices of the face of the triangle are positively charged, that's because hydrogen is less electronegative than oxygen and, hence, the two hydrogen atoms are partially positively charged in a water molecule.

Oxygen is more electronegative than hydrogen meaning it has a greater electron-withdrawing force, so electrons are closer to oxygen within the O-H bonds. Oxygen, as a result, becomes partially negatively charged, so it's our negative pole of the magnet.
