(A) The oxygen atom becomes strongly negative.
Explanation:
When a very electronegative atom like oxygen bonds to an atom with a lower electronegativity, like lithium, the oxygen atom becomes strongly negative and the lithium becomes strongly positive.
The attraction between these oppositely charged ions results in the formation ionic bond.
- An ionic bond is an interatomic bond in which a highly electronegative atom is bonded to less electronegative one.
- The electronegative nature of the oxgyen allows is to gain the electrons lost by weakly electronegative lthium.
- Most metals have low electronegativity.
- They then both will form ions.
- The attraction between the oppositely charged ions results in an ionic/electrovalent bonding.

Answer:
1.4s
Explanation:
Given parameters:
Mass of ball = 2kg
Force = 8N
Time = 0.35s
Unknown:
Change in velocity = ?
Solution:
To solve this problem, we use the expression obtained from Newton's second law of motion which is shown below:
Ft = m(v - u)
So;
Ft = m Δv
F is the force
t is the time
m is the mass
Δv is the change in velocity
8 x 0.35 = 2 x Δv
Δv = 1.4s
Ionic bonding is the bonding between a positive metal with a negative nonmetal (metals are always positive while non metals are opposite). The meeting of a metal with a non metal creates an ionic bond.
