The answer is A. An sp3 hybridized atom will have a total of 4 single bonds and lone pairs. Since carbon here is attached to four hydrogens, it must be sp3 hybridized. The C-H bonds are also the least polar bonds here, even though there is a slight amount of electronegativity difference between the two.
Carbon have 4 valence electron
The electron configuration of C is : 1s2 2s2 2ps
the outer most s and p orbital contains 4 electrons and these are the valence electron of C atom
Key: to determine the valence electron of an element, you have to refer to the group it is located in, in the periodic table. (C is in group 4 (or 14) so VE = 4)
hope its clear enough
Answer:
The correct option is: b. the elements in the material are well apart (in different sides) in the periodic table
Explanation:
Ionic bond is a type of chemical bonding that is formed by the transfer of electrons from one atom to another. It is formed between atoms having large electronegativity difference.
The more electronegative atom accepts electrons and becomes a negatively charged anion. Whereas, the less electronegative atom loses electrons and becomes a positively charged cation.
<u>Simply, an ionic bond is formed when the electrons are transferred from a metal to a non-metal, which are present on different sides of the periodic table.</u>
