Answer:
<u>Valence electrons are always located in the outer most energy level.</u>
Explanation:
Valence electrons are the ones that are involved in chemical bonds. In order to take part in a chemical bonding, the outermost/valence electron needs to be involved. Thus, the answer is <u>Valence electrons are always located in the outer most energy level.</u>
An atomic nucleus . . .
-- contains all of the atom's positive charge
-- contains almost all of the atom's mass
-- contains none of the atom's negative charge.
Answer:
The correct answer is B. 0.64 m/s²
Explanation:
According to the Newton's Second law of motion acceleration of an object by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.
Mathematically,
F ∝ a
F = ma
Given data:
Force = F = 35 N
Mass = m = 55 kg
acceleration = a = ?
F = ma
a = F/m
a = 35/55
a = 0.64 m/s²
