How are heterogeneous mixtures and solutions different?

1 answer:

4 0

Both are considered mixtures - that is, they are made up of two or more pure substances. ... A heterogeneous mixture appears to be made of different substances. A solution appears the same throughout. In the fluid phase (gas or liquid, or any combination of those) a solution is transparent (thought not colourless).

If you were to use Lewis theory to predict the formula for the compound between rubidium and fluorine, it would most likely be:

goldenfox [79]

<u>Answer:</u> The formula of the compound formed between rubidium and fluorine is RbF

<u>Explanation:</u>

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Rubidium is the 37th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^1$

This will loose 1 electron to form $Rb^+$ ion

Fluoride is the 9th element of the periodic table having electronic configuration of $1s^22s^22p^5$

This will gain 1 electron to form $F^-$ ion

To form $RbF$ compound, 1 rubidium ion is needed to neutralize the charge on fluoride ion

The formation of the given compounds is shown in the image below.

What is the electron structure of a beryllium atom?

levacccp [35]

From the periodic table, beryllium has an atomic number 4. This means that beryllium has 4 electrons.

Now, the first energy level can hold only 2 electrons (which will occupy the s sublevel) wile the remaining two electrons will occupy the second energy level (also in the s sublevel).

Based on the above, the electronic configuration of beryllium will be as follows:
1s2 2s2
