All I have done here is to use $"the Periodic Table"$, a copy of which you will always have available in every exam in chemistry and physics you will ever sit. If you are doing your chemistry homework, there should be a copy in front of you. Can you tell me the other metals in rhodium's group, in the vertical column of ?

Note that the actual electronic configuration is different to the one given in the problem. Neverthless, if there are 45 electrons, the NEUTRAL element must be $"rhodium metal"$.

What is the electron configuration of an element with atomic number 8?

Well, once you get your periodic table out, spot the element with $Z = 8$... and you should find it is oxygen. It is on period 2, column 16....

The work function of an element is the energy required to remove an electron from the surface of the solid element. The work function for lithium is 279.7 kJ/mol. What is the maximum wavelength of light that can remove an electron from an atom ?

The maximum of light that can remove an electron from a lithium atom is equal to $4.279 * 10^(-7)"m"$. So, you know that the work function of lithium, which is...

How do you read the Electron Configuration Periodic Table? For example, if yu wanted to find Mg what would its configuration be?

Subshell notation of magnesium is 2.8.2. We know that magnesium is in Group 2, Period 3. Hence it has an energy level of 3. By doing this, we can...

A sodium atom has an electron configuration of $1s^2 2s^2 2p^6 3s^1$. If the sodium atom becomes ionized, its new electron configuration will be the same as which element?

If the sodium is ionised, the outer $3s^1$ electron is lost, so the configuration becomes $1s^2 2s^2 2p^6$, which is the same as neon, $Ne$.

The electron configuration for magnesium is $1s^2 2s^2 2p^6 3s^2$. What is the distribution of electrons in the electron shells of a magnesium atom?

You have filled 2 shells, and begun a third valence shell. Is this all you want, or have I missed the point?

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?

$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....
