Interpretation & Concept Introduction:
Which of the five given elements has fewest protons per nucleus.
Answer to Problem 2.1VP
Solution:
The element highlighted in purple color (Hydrogen) has fewest protons per nucleus.
Explanation of Solution
The location of an element in the periodic table is determined by its
Purple color – Hydrogen – atomic number 1 – 1 proton
Blue color – Helium – atomic number 2 - 2 protons
Green color – Fluorine – atomic number 9 - 9 protons
Yellow color – Sulfur – atomic number 16 – 16 protons
Green color – Arsenic – atomic number 33 – 33 protons
Conclusion:
The number of protons in the nucleus of an element is the same as its atomic number. The position of the element in the periodic table is also determined by its atomic number. Using this, we can see that of the five elements shown, hydrogen (Purple Square) has the least protons per nucleus.
