The _ _ states that electrons fill orbitals starting at the _ energy level and building themselves _ to higher energy levels.

a. hope i'm right

explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

a chemical change results in a new substance being formed; whereas a physical change will result in a different state of matter
