Answer: dispersion forces, dipole-dipole and hydrogen bonds
Explanation:
A or b sorry if I’m wrong
Answer:
D. A²⁺
Explanation:
Element from Group 2A -
The element of group 2A are known as the alkaline earth metals ,
The elements of this group are - beryllium (Be) , magnesium (Mg) , calcium (Ca) , strontium (Sr) , barium (Ba) , and radium (Ra).
The valence shell of these elements have two valence electrons and therefore , if the element need to stabilizes itself , it need to lose these two electrons and attain noble gas configuration,
Therefore ,
After losing the two electrons , the element becomes A²⁺.
Hence , the ions are symbolized as A²⁺.
It seems that you have missed the given options for this question, but anyway, the correct answer is NONE OF THE ABOVE. None of the molecules given must be shown with resonance structures. A resonance structure is defined as the way or presenting <span>delocalized electrons within certain molecules or polyatomic ions. This bonding cannot be expressed by one single Lewis </span><span>structure. Hope this answer helps.</span>
