An imaginary element, "X" has an atomic number of 43 and a mass number of 85.00201. How many protons does a neutral atom of this element contain?

Solutions

Expert Solution

In a neutral atom, number of protons is equal to its atomic number.

So, the element with the atomic number 43 is technitium. Therefore, the number of protons in Tc is 43.

The element technetium (atomic number 43) is radioactive and one of its isotopes, 99Tc, is used in medicine for diagnostic imaging. The isotope is usually obtained in the form of the pertechnetate anion, TcO4-, but its use sometimes requires the technetium to be in a lower oxidation state. Reduction can be carried out using Sn2+ in an acidic solution. The skeleton equation is TcO4- + Sn2+ → Tc4+ + Sn4+ (acidic solution) Balance the equation by the ion–electron method.

Each element has a unique atomic number, which is listed on the periodic table above the chemical symbol for the element. The atomic number is equal to the charge on the nucleus. The atomic number also equals the number of protons in the nucleus and the number of electrons in the neutral atom of the element. For example, Fluorine (F) has the atomic number 9, which means that its atoms contain 9 protons and 9 electrons. Zinc (Zn) has the...
