Which substance has two neutrons?<br><br> A. H-2<br><br> B. He-2<br><br> C. He-3<br><br> D. He-4
Feliz [49]

Answer:

D

Explanation:

In a Helium (He) atom, the atomic structure of the atom has 2 protons, 2 electrons and 2 neutrons. For an element X to be a Helium (He) atom, it must possess 2 protons. The number of neutrons present will determine its stability either if its probably radioactive or a natural occurring inert gas.

In option 1,

We have H-2. The symbol "H" is used to denote the element hydrogen in the periodic table and hydrogen has only 1 protons and 1 neutron making its mass number 2.

Option 2,

He -2 : here in this option, we have a helium atom, but with mass number of 2 only. Judging from the formula of mass number = protons + neutrons, we already have proton as 2, hence the number of neutrons there is zero (0)

Option 3,

He - 3 : just like in option 2, the only difference here is that the mass number is 3 hence making the number of neutrons just 1.

Option 4,

He - 4 : This option met the requirements of having 2 protons and 2 neutrons making a total of 4 which corresponds to the mass number.

We refer to astronauts in space as weightless, but not without mass. Why?
fredd [130]
Weight is the force exerted by the gravity on that object, therefore when an astronaut is in space with no gravity he is weightless. Mass is the actual amount of matter contained in a body, this won’t change if the gravity changes.
