Here’s how we find the valency of chlorine (Cl), sulfur (S), and magnesium (Mg):
Chlorine (Cl):
– Chlorine belongs to Group 17 (or Group VIIA) of the periodic table.
– It has 7 electrons in its outer shell (2s² 2p⁶ 3s² 3p⁵).
– To achieve a stable electron configuration like the noble gas neon (with 8 electrons in its outer shell), chlorine tends to gain 1 electron.
– Therefore, the valency of chlorine is -1.
Sulfur (S):
– Sulfur is in Group 16 (or Group VIA) of the periodic table.
– It has 6 electrons in its outer shell (2s² 2p⁶ 3s² 3p⁴).
– Sulfur needs 2 more electrons to achieve a stable electron configuration, similar to the noble gas argon (with 8 electrons in its outer shell).
– Thus, the valency of sulfur is -2.
Magnesium (Mg):
– Magnesium belongs to Group 2 (or Group IIA) of the periodic table.
– It has 2 electrons in its outer shell (3s²).
– Magnesium tends to lose these 2 electrons to achieve a stable electron configuration, akin to the noble gas neon (with 8 electrons in its outer shell).
– Hence, the valency of magnesium is +2.
Valency signifies the combining capacity of an element based on its ability to gain, lose, or share electrons to attain a stable configuration. This understanding helps predict how elements interact and form compounds during chemical reactions.

(i) The atomic number of an atom is determined by the number of protons it contains. In this case, you mentioned that the number of protons is 8. The atomic number is equal to the number of protons in the nucleus of an atom. Therefore, the atomic number of the atom in question is 8.
(ii) The charge on an atom is determined by the balance between the positively charged protons and the negatively charged electrons. If the number of electrons is equal to the number of protons, the atom is electrically neutral. In this scenario, both the number of electrons and the number of protons are 8, indicating that the charges balance each other out. Thus, the charge on the atom is neutral (0).
Hydrogen (H) typically has 1 proton and 1 electron in its nucleus, making it the simplest form of hydrogen. Deuterium (D) is an isotope of hydrogen with 1 proton and 1 neutron in its nucleus, alongside 1 electron.

Hydrogen (H) typically has 1 proton and 1 electron in its nucleus, making it the simplest form of hydrogen. Deuterium (D) is an isotope of hydrogen with 1 proton and 1 neutron in its nucleus, alongside 1 electron. Tritium (T), another hydrogen isotope, has 1 proton and 2 neutrons in its nucleus, along with 1 electron.
These variations in the number of neutrons among isotopes result in different atomic masses for each isotope of hydrogen.

**Isobars:**
Isobars are atoms of different elements that have the same mass number (total number of protons and neutrons) but different atomic numbers. As a result, they have different electronic configurations.

Electrons:
1. Charge: Electrons carry a fundamental negative charge (-1.6 x 10^-19 coulombs), which is equal in magnitude but opposite in sign to the positive charge of protons.
2. Mass: Electrons have a significantly smaller mass compared to protons and neutrons. Their mass is approximately 9.109 x 10^-31 kilograms, roughly 1/1836 times the mass of a proton or neutron.
3. Location: Electrons are distributed around the atomic nucleus in specific energy levels or shells. They occupy orbitals within these energy levels based on their energy and quantum states.
4. Behavior: Electrons play a vital role in chemical reactions and bonding. Their movement between energy levels determines an atom’s reactivity and ability to form chemical bonds.
Protons:
1. Charge: Protons carry a positive charge equal in magnitude to the negative charge of electrons (+1.6 x 10^-19 coulombs). This positive charge defines the identity of an atom.
2. Mass: Protons have a relatively larger mass compared to electrons. Their mass is approximately 1.673 x 10^-27 kilograms, similar to the mass of neutrons.
3. Location: Protons are located within the atomic nucleus, densely packed at the center of the atom.
4. Role: The number of protons in an atom’s nucleus determines its atomic number, identifying the element. Protons also contribute to the stability of the nucleus through the electromagnetic force.
Neutrons:
1. Charge: Neutrons are electrically neutral, meaning they have no net charge. They do not possess any positive or negative charge.
2. Mass: Neutrons have a mass similar to that of protons. Their mass is approximately 1.675 x 10^-27 kilograms.
3. Location: Neutrons, like protons, are situated within the atomic nucleus, alongside protons.
4. Role: Neutrons play a crucial role in maintaining the stability of the atomic nucleus. They help bind protons together through the strong nuclear force, preventing the electromagnetic repulsion between positively charged protons.
In summary, electrons, protons, and neutrons are fundamental particles with distinct properties. They contribute to an atom’s structure, properties, and behavior, with electrons determining chemical behavior, protons defining the element’s identity, and neutrons contributing to nuclear stability.
