Question

question 6 (1 point)
a carbon atom has _i_valence electrons and can form covalent bonds with up to _ii_other atoms. the statement given above is completed by the information given in the row:
row i ii
a 1 2
b 2 2
c 3 4
d 4 4
e 4 3
a) a
b) b
c) c
d) d
e) e

Explanation:

Carbon has an atomic number of 6. Its electron configuration is \(1s^{2}2s^{2}2p^{2}\). The valence electrons are in the \(n = 2\) shell. The number of valence electrons is \(2 + 2=4\). Since each covalent bond involves one valence electron from carbon (and one from the other atom), carbon can form up to 4 covalent bonds (as it has 4 valence electrons to share).

Answer:

d) D
