Agroup of students working in a high school chemistry lab believe they have discovered a new element! how exciting! upon further testing by scientists (with better equipment), it is found that the new element contains 74 protons and 110 neutrons. use page 495 and the periodic table (pages 500-501) to answer the following questions about this new element.
1. what is the atomic number of this element? ¬¬
2. what is the mass number of this element?
3. is this really a new element? explain your reasoning.
4. give the name and symbol for this
5. when the students discovered it, did they find a solid, a liquid, or a gas? explain your reasoning.

Explanation:

We are given that  number of protons in  new element =74

Number of neutrons in new element =110

We know that

1.Atomic number = Total number of protons

Atomic number of new element =74

Mass number = Number of protons+number of neutrons

2.Mass number of new element =74+110=184

3.It is not new element .It had already exits in periodic table.

4.Hence, the new elements is tungsten or wolfram.

Symbol of tungsten is W.

5.It is a metal and all metals except mercury are solids.Therefore, tungsten is a solid.
