Can someone help me ? I choice the element Xenon Xe

Xenon is element 54. in a perfect atom it would have 54 neutrons

refer to explanation in order V

Explanation:

Atomic number: 54

Protons: 54

Electrons: 54

Neutrons: 77

Mass Number: 131.293 U

6 (1/2): At the upper left is the atomic number, or number of protons. In the middle is the letter symbol for the element (e.g., H). Below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. At the very bottom is the name of the element (e.g., hydrogen).

6 (2/2): On the periodic table, the mass number is usually located below the element symbol.

I hope this helped!

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.
