Question

Complete the following table

Atomic number	Mass number	Number of neutrons	Number of protons	Number of electrons	Name of the atomic species
9	-	10	-	-	-
16	32	-	-	-	Sulphur
-	24	-	12	-	-
-	2	-	1	-	-
-	1	0	1	-	-

Answer 1

Atomic number and mass number are always whole numbers because they are obtained from the counting of electrons, protons and neutrons. The sum of atomic number and mass number gives us the total number of subatomic particles present in the atom.

Complete Step by step solution: To complete the table let's discuss the terms included in the table:
-Atomic number: Atomic number is generally represented by the symbol Z and in an atom atomic number is equal to the number of protons given in the system.
-Mass number: Mass number of an atom is represented by A and it is generally the total number of protons and neutrons present in an atom. In most of the cases it has double the value from the mass number.
-Neutrons: Neutrons are generally neutral in nature and present inside the nucleus.
-Protons: Protons are positively charged species which generally show atomic number and are present inside the nucleus.
-Electrons: Electrons are generally negatively charged atoms which revolve around the nucleus.
-Name of the species: It generally depends upon the atomic number as species are arranged on the basis of atomic number in periodic table.
Hence by knowing all the terms completion of table becomes very easy and it is filled as:

Atomic number	Mass number	Number of neutrons	Number of protons	Number of electrons	Name of the atomic species
9	19	10	9	9	Fluorine
16	32	16	16	16	Sulphur
12	24	12	12	12	Magnesium
1	2	1	1	1	Deuterium
1	1	0	1	0	Protium

Note: Deuterium and protium are generally isotopes of hydrogen. Isotopes are those atoms, molecules or species which have the same number of protons or we can say the same atomic number but different numbers of neutrons or have different mass numbers.
