the element is Ca with atomic number 20
Nuclear power plants real ease energy by FISSION
(this is the process when a heavy, unstable atomic nucleus splits into 2 or more lighter elements. This process releases lots of energy.)
I hope this helped you out! :)
Answer:
357.475
Explanation:
First you need periodic table and you have to look for mass
Fe = 3 x 55.845 = 167.535
P = 2 x 30.97 = 61.94
o = 4 x 2 so 8 oxygen = 8 x 16 = 128
add all and you get 357.475
A scientific law is a statement that is universally accepted and answers the "how?" question.
Hope this helps!
Answer:

Explanation:
some common physical properties they have is that they are all soilds (at room temperature), they are malleable (easily bent/shaped) and ductile, and they are good conductors of heat and electricity. they also have high melting points and have a metallic appearance.
