A toxicity is answer for that question
The element to which this atom belongs is a p-block main-group element.
What is general electronic configuration?
Electronic configuration or general electron configuration or electronic structure of atoms or ions is the arrangement of orbital energy levels for s, p, d, and f-block elements of the periodic table.
Which group are p-block elements in the periodic table write the general electronic configuration of a p-block element?
Groups 13, 14, 15, 16, and 17 elements comprise the p-block elements. The general configuration of p-block elements is ns2np(1−6).
What is the general configuration of p- block elments?
The general electronic configuration of p-block elements is ns2np1-6 (Except Helium). The number of electrons in the p-block element's penultimate shell is either 2 or 8 or 18.
Therefore, the element belongs to the p-block.

It bonds to skin because
solid polymer requires the presence of water to get things started, be it in the air or on your skin. Without a little moisture, SuperGlue can't bond anything. This explains why the glue is so good at sticking fingers together.
It's quite hard to explain without an example, but I'll give it a go:
Basically, you have to count the number of an element on one side of the equation, then count it on the other, and the aim of balancing the equation is to get the 2 values to be the same (as mass cannot be created or destroyed).
This involves multiplication of the molecule(s) on either side of the equation in order to balance the whole thing. Note this is not like maths, you dont have to do the same to both sides, but you <em>do</em> have to multiply out <em>entire molecules</em> - you cannot multiply just the H2 in H2O for example.
A reasonably basic example of this balancing is:
Fe + Cl2 = FeCl3
The first thing I notice is that there is an even number of Cl atoms on the left, and an odd number on the right, so the first thing I'll do is multiply the one on the right to get it to an even number, ie by 2.
Fe + Cl2 = 2(FeCl3)
Expanding that gives Fe2Cl6 (although you dont write it like that). So we need to get 6 Cl atoms and 2 Fe atoms by multiplying the left hand molecules by amounts if possible. If you look at that, we can achieve that, by multiplying Cl2 by 3, and Fe by 2.
2Fe + 3Cl2 = 2FeCl3
And there you have your balanced equation, you'll notice that the number of any given element has the same number of atoms on both sides of the equation.
Answer:
P is the limiting reagent
Explanation:
P = phosphorus = 30.97g/mol
Cl2 = Chlorine = 70.91g/mol
PCl3 = Phosphorus Trichloride = 137.33g/mol
P + Cl2 = PCl3
Left Side
P = 1
Cl = 2
Right Side
P = 1
Cl = 3
So equation needs to be balanced first
2P + 3Cl = 2PCl3
Left Side
P = 2
Cl = 6
Right Side
P = 2
Cl = 6
That's better.
Ok so we have 12.39g of P so we have 0.4 moles of it
We then have 52.54g of Cl so we have 0.74 moles of it
For every P we need 1.5 Cl so we have an excess of Cl
