Element x is found in group 2A and element Y in group 5A how many electrons are transferred when these elements form a compound
No electrons are transferred since both elements need to gain 2 valence electrons to attain octate state so the two elements will share the outer electrons in their outer ring....

<pre class="editor-code"><code class="prism">With the increase of the atomic number within the same period, the atomic radius of the elements decreases because?</code></pre>
As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell, causing the atomic radius to decrease due to the increasing...

why d-block elements elements are called as outer transition elements and f-block elements as inner transition elements?
The d-block elements are called transition metals and have valence electrons in d orbitals. The inner transition elements are those who have their last 3 shells incompletely filled. The f...

The atomic number of an element x is 14 and it's relative atomic mass is 28 how many electrons does an atom of x contains
Silicon is a chemical element with the symbol Si, atomic number 14 and relative atomic mass 28. So, in our case X is the Silicon (Si). Silicon-28 is a stable...

Natural boron is composed of two isotopes: 19.78% boron-10 (atomic mass = 10.0129 amu) and 80.22% boron-11 (atomic mass = 11.0093 amu). What is the average atomic mass of naturally occurring boron?
Average atomic mass=(19.78%*10.0129amu + 80.22%*11.0093amu)/100%=10.8122amu
