Question

Identify the element for each of the following atomic numbers. (remember Z=atomic number and

where can atomic number be found?!)
Z=98
Z= 47
Z = 83
Z=17
Z=44

Answer 1

Each element has a unique atomic number (Z) representing the number of protons in its nucleus. The elements with atomic numbers Z=98, Z=47, Z=83, Z=17, and Z=44 correspond to Californium (Cf), Silver (Ag), Bismuth (Bi), Chlorine (Cl), and Ruthenium (Ru) respectively. These numbers can be found on the periodic table above the elemental symbols.

Step-by-step explanation:

The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element and is used to define the identity of the element. For the atomic numbers provided:

• Z=98 corresponds to Californium (Cf).
• Z=47 corresponds to Silver (Ag).
• Z=83 corresponds to Bismuth (Bi).
• Z=17 corresponds to Chlorine (Cl).
• Z=44 corresponds to Ruthenium (Ru).

The periodic table is a tool where each element is represented by a unique symbol, and is ordered in increasing atomic number. The atomic number can be found above the element's symbol on the periodic table. In a neutral atom, the number of electrons is equal to the number of protons, which is reflected by the atomic number.
