SUMMARY

The isotopic formula for the diatomic element X2, which contains 34 moles of electrons and 40 moles of neutrons, is determined to be 17X37. This notation indicates that each atom of element X has an atomic number of 17 (derived from the 34 moles of electrons) and an atomic mass of 37 (sum of protons and neutrons). The calculation confirms that there are 17 electrons and 20 neutrons per atom, leading to the conclusion about the isotopic representation.

PREREQUISITES
  • Understanding of atomic structure, including protons, neutrons, and electrons.
  • Familiarity with the mole concept in chemistry.
  • Knowledge of isotopes and how to represent them in notation.
  • Basic arithmetic skills for calculating atomic mass and number.
NEXT STEPS
  • Study the mole concept in detail, focusing on its applications in chemistry.
  • Learn about isotopes and their significance in chemical reactions.
  • Explore atomic structure and the relationship between atomic number and mass.
  • Investigate the periodic table and how isotopic notation is used for various elements.
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding isotopic formulas and atomic structure in detail.

1mole of diatomic element X2 contains 34 and 40 moles of electrons and neutrons respectively, the isoptopic formula of the element is?

Homework Statement


1mole of diatomic element X2 contains 34 and 40 moles of electrons and neutrons respectively

Homework Equations


all the basic ones!

The Attempt at a Solution


The answer from my point of view should be 17X37

Looks good.
 


I am assuming that the isotopic formula of the element asks you for that notation where you display both the atomic mass (protons + neutrons) and atomic number (protons).

Something like 1H1

Then, let's start from the beginning.

34 moles of electrons in X2 = 17 electrons in one atom.
Similarly, 20 neutrons in one atom.

-------------------

With this in mind, what will be the atomic mass? What will be the atomic number?
