Which of the following is a common property of Noble Gases?
2 answers:
Answer: the property of noble gases which is common is that they have a full outer shell of electrons.
Explanation:
Noble gases are the gases belonging to Group 18 of the periodic table. The electronic configuration for these gases are:
From the electronic configuration, it is visible that they have fully filled outer shell and hence, these gases are least reactive of all the elements in the periodic table.
As, they are not reactive and therefore they do not form any chemical compounds easily.
From the electronic configuration, it is visible that there are no free electrons in these gases, therefore, they are not good conductors of electricity.
Hence, the correct answer is that they all have full outer shell of electrons.

let the mass of Venus is M then mass of Saturn is 100 M
similarly if the radius of Venus is R then the radius of Saturn is 10 R
now the force of gravity on a man of mass "m" at the surface of Venus is given by
now similarly the gravitational force on the man if he is at the surface of Saturn
so here if we divide the two forces
so here we can say
F1 = F2
so on both planets the gravitational force will be same
Answer:
the weight of the object decreases when it is taken from the Earth to the Moon
Explanation:
The weight of an object is defined as the product of the mass of the object with the acceleration due to gravity of the Planet.
where,
W = weight of the object
m = mass of the object
g = acceleration due to gravity on the planet
The mass of an object remains constant everywhere in the universe. Therefore, the weight is directly proportional to the value of acceleration due to gravity.
The value of acceleration due to gravity on the Moon is lesser than its value on the Earth.
<u>Hence, the weight of the object decreases when it is taken from the Earth to the Moon </u>
