Please help me where I should put these

The red one is an electron, the ring is the nucleus, the blue one is a proton, the yellow one is a neutron.

The red one is electron since it is in the outer part of the atom.

The black ring is nucleus since it is where the protons are nuetrons are enclosed in.

The blue one is proton, since the number of electrons is equal to the number of protons.

Therefore, the last one, yellow, is Neutrons.

Hope u understand

Please mark as brainliest

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

95.03 is the answer. hope this !
