Question

Strontium is the only element discovered in
Scotland. Which of these events/activities is not
linked to strontium?​

Answer 1

Answer:

Isotopes of the same element will have the same atomic number but different mass numbers. ... For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4).
