In the ground state, each atom of an element has two valence electrons. This element has a lower first ionization energy than calcium. Where is this element located on the Periodic Table?
It is a period or row that is energy level five or more, below calcium on . Two valence electrons places the element in the alkaline earth family or...

If each orbital can hold a maximum of 3 electrons, the number of elements in the 4th $bb"[period of the]"$ periodic table (long form) is?
Well, this is kind of open to interpretation... but if I interpreted it correctly, I get $27$ , compared to the original $18$ elements, in the 4th period of ....

A particular element is located in column IVA of the periodic table. How many dots would be placed around the symbol of this element in its electron dot notation?
Column IVA is group 14 on . The in group 14 all have 4 , so the Lewis symbol for elements in this group have 4 dots around them (each...

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, $Ne$.

What is the position of an element in the periodic table if its electron configuration is $1s^2 2s^2 2p^6 3s^2 3p^5$?
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...
