Cooper is the substance that can't be decomposed by a chemical chAnge. So 4)
<h3>Answer:</h3>
This atom has 80 protons, 120 neutrons and 80 electrons.
<h3>Explanation:</h3>
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore. As given, the atomic number is 80 therefore, Hg contains 80 protons respectively.
Number of Electrons:
As given in statement, Hg is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 80 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 200
So,
No. of Neutrons = 200 - 80
No. of Neutrons = 120
Answer:
eight strong bonds to the atoms that it touches and six weaker bonds to the atoms it almost touches. This makes it easier to understand why a metal might prefer the body-centered cubic structure to the hexagonal or cubic closest-packed structure.
Answer: Force disadvantage and distance advantage
Explanation: When mechanical advantage is less than one the force of the strength decreases because input force is greater than output force.
The distance increases ie the object is moving over a long distance.
Example when fishing with a long fishing rod the force applied to move the fish from the water is greater than the weight of the fish itself. The advantage of using the long fishing pole is that the distance over which the fish travels is greatly increased.
Hope this helps. It took me about half an hour before I could get this answer from my various searches. The idea might not be clear but this was what I was able to understand.
