How do you remember it's Group 2. Well the best way is to consult a Periodic Table, and note the position of $Mg$, $Group$ $2$, and $Period$ $3$.

You should be issued with a Periodic Table in every Chemistry and Physics examination for which you ever sit.

An average sample of chlorine contains 75.77% chlorine-35, with an atomic mass of 34.969 amu (atomic mass units), and 24.23% chlorine-37, with an atomic mass of 36.966 amu. What is the average atomic mass of chlorine?

The weighted average is the sum of each individual nuclide, multiplied by its isotopic abundance. So, we simply do the arithmetic: $0.7577xx34.969+0.2423xx36.966 = ???$ amu Then look at to...

How would you explain how period and group trends in atomic radii are related to electron configuration?

Atomic radii DECREASE across a Period, but increase down a Group. Why? As we add another proton to the nucleus we add another electron to the valence shell. As we...

Beryllium has an atomic number of $2$. What is its electron configuration? Will it lose $2$ electrons or gain $6$ to form an ion?

It wants the configuration that helium has, which is two . To be more specific, it wants a DUET, not an octet. Beryllium ($"Be"$) has the $4$ (not $2$),...

What is the electron configuration for an excited atom of phosphorous, ready to emit a photon of energy and return to ground state? (configuration has to follow all rules except be in lowest energy)

Phosphorus has $15$. As such its electronic configuration in ground state is $1s^2 2s^2 2p^6 3s^2 3p^3$ The following electronic configurations could be excited states $1s^2 2s^2...

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 mixture of magnesium carbonate and magnesium oxide of mass $12.46*g$ underwent fierce heating. After heating, there were $8.43*g$ of salt remaining. What were the masses of magnesium carbonate, and magnesium oxide in the original sample?

$MgCO_3(s)+DeltararrMgO(s) + CO_2(g)$ And we would have to heat the magnesium salt VERY fiercely to get complete decarboxylation. $"Moles of carbon dioxide LOST"$ $=$ $(4.40*g)/(44.01*g*mol^-1)$ $=0.010*mol$ And therefore in...
