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

The 100 or so are characterized by $Z_"atomic number"$...which specifies the number of charged particles present in the element's nucleus. $"Z=1, hydrogen; Z=2, helium"$ $"Z=3, lithium; Z=4, beryllium; Z=5, boron;...

As we face , increases ACROSS the Period from LEFT to RIGHT, BUT DECREASES down a Group, a column of the the Periodic Table. So why? Well, we will first...

Group 1 A ($ s^1$) has one valence electron. Group 2 A ($ s^2 $) has two . Group 8 A ($ s^2p^6 $) has eight valance electrons....

Element with valence shell electronic configuration $"ns"^2\ "np"^(1-6)$ belongs to p-block Valence shell electronic configuration of all the groups of p-block are shown below $underline(bb( color(white)(..)"Group no."color(white)(..............) "E.C" color(white)(..))$ $color(white)(.....)...

Potassium is the first element in the fourth period and its is $["Ar"]4"s"^1$.

$"For main group elements, the column, the Group number"$$"........represents the number of valence electrons."$ Hydrogen is in $"Group I"$, and has the one valence electron. Chlorine is in $"Group...

For simple explanation I will talk about only a representative element such as : 11Na : 1$s^2$ 2$s^2$ 2$p^6$ 3$s^1$ 19K : 1$s^2$ 2$s^2$ 2$p^6$ 3$s^2$ 3$p^6$ 4$s^1$ you can...

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 common electronic configuration of the p block elements is $nS^2nP^(1-6)$ Here $n=3$ and the condition is maintained. Hence we get that the period of the element of the...

Your tool of choice here is the dilution factor, $"DF"$, which tells you The ratio that exists between the volume of the diluted solution and the volume of...
