I think the correct answer is the second option. The statement pertaining to the properties of the element vanadium is reliable because the facts presented are testable or can be verified by doing experimentation. Also, nowadays, many studies are present that contains properties of almost anything.

Hydrogen has one proton in it's nucleus but exists as three isotopes.
murzikaleks [220]
The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.

Example,

                                                 ᵇₐX
                        
                                   Where;
                                                b = Mass Number
                                                a = Atomic Number
                                               X  = Symbol
For Hydrogen Isotopes:

1) Protium: 1 Proton , 0 Neutron

                                                ¹₁H

2) Deuterium: 1 Proton , 1 Neutron

                                                ²₁H

3) Tritium: 1 Proton , 2 Neutron

                                                ³₁H

What is the volume of a piece of aluminum if the mass is 150g and the density.is 2.70 g/cm3
zepelin [54]

Answer:

The answer is

<h2>55.56 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of aluminum = 150 g

density = 2.7 g/cm³

The volume is

volume =  \frac{150}{2.7}  \\  = 55.5555555...

We have the final answer as

<h3>55.56 cm³</h3>

Hope this helps you

What are the prompt neutrons that occur during nuclear fission?
zysi [14]

Answer:

Prompt Neutrons

Explanation:

Principle. Using uranium-235 as an example, this nucleus absorbs thermal neutrons, and the immediate mass products of a fission event are two large fission fragments, which are remnants of the formed uranium-236 nucleus. These fragments emit two or three free neutrons (2.5 on average), called prompt neutrons.
