Group 2 elements have two valence electrons. Which kind of bond will they most likely form, and why?(1 point) A covalent bond is likely because they want to share those two valence electrons in order to become stable.

An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

An ionic bond is likely because they are metals and will want to bond with nonmetals.

A metallic bond is likely because they are metals and can bond with other metals.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
