Imagine an atom as a tiny solar system, with electrons orbiting around a nucleus like planets orbiting the sun.
Now, atoms have different layers or ‘shells’ where these electrons reside. The two innermost shells are commonly named K and L shells. Each shell has a specific capacity for electrons.
The K shell, being the closest to the nucleus, can hold up to 2 electrons. Moving outward, the L shell, the next electron layer, can accommodate a maximum of 8 electrons.
So, what happens if both the K and L shells are completely full, packed with the maximum number of electrons they can hold?
Well, in this scenario, the K shell is holding its maximum of 2 electrons, and the L shell is also at its limit with 8 electrons.
To find the total number of electrons in this atom, we simply add up the number of electrons in the K and L shells: 2 (from the K shell) + 8 (from the L shell) equals 10 electrons in total.
Therefore, if an atom’s K and L shells are completely filled, the total number of electrons in that atom would be 10. This knowledge helps us understand how many electrons an atom can hold in its specific electron shells, guiding us in unraveling the mysteries of chemistry and the behavior of elements!”
Understanding the electron arrangement within atoms, especially regarding shell capacities, is crucial in comprehending the behavior and reactivity of elements in various chemical reactions.

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.

J.J. Thomson’s plum pudding model was a significant step forward in understanding the atom, but it had several limitations:
1. Absence of a Central Nucleus: In Thomson’s model, he envisioned the atom as a uniform, positively charged sphere with embedded electrons, resembling plums within a pudding. However, this model didn’t account for a central nucleus. Later experiments, like the Rutherford gold foil experiment, showed that the atom has a small, dense nucleus at its center, which Thomson’s model failed to include.
2. Explanation of Atomic Stability: The model couldn’t explain why electrons, which carried negative charges, didn’t collapse into the positively charged nucleus. According to classical physics, accelerating charged particles lose energy as radiation and should spiral into the nucleus. This model lacked an explanation for why atoms didn’t collapse, raising questions about atomic stability.
3. Spectral Lines: The model couldn’t explain the specific discrete wavelengths observed in atomic spectra. Elements emit or absorb light at distinct wavelengths, creating spectral lines. Thomson’s model couldn’t account for why these specific wavelengths were emitted or absorbed by different elements.
4. Variation in Element Properties: It didn’t provide insight into why different elements have unique chemical properties. The arrangement of electrons within atoms determines an element’s chemical behavior, but Thomson’s model didn’t address how this arrangement varied among elements.
5. Neglect of Neutrons: Thomson’s model focused solely on electrons within a positively charged sphere and didn’t consider neutrons. Later discoveries revealed that neutrons are present in the atomic nucleus, contributing to its stability, but this was not part of Thomson’s model.
These limitations prompted further experiments and the development of new atomic models that addressed these issues, leading to the development of models like the Bohr model and eventually quantum mechanics, providing a more accurate description of atomic structure and behavior.

Charge of an Atom with One Electron and One Proton:
– Normal Atom: In a neutral atom, the number of protons (positively charged particles) equals the number of electrons (negatively charged particles), resulting in a balanced charge, and the atom remains electrically neutral.
– Scenario Description: An atom containing only one electron and one proton lacks an equal number of electrons to balance the charge of the proton.
– Unbalanced Charge: With one proton (+1 unit) and one electron (-1 unit), there’s no additional electron to counterbalance the proton’s positive charge.
– Resultant Charge: In this case, the atom would carry a net positive charge of +1 unit, as the positive charge of the proton remains unopposed by an equivalent negative charge.
– Identification: Such an atom, with an unbalanced charge, would be referred to as a positively charged hydrogen ion.
Conclusion:
An atom with only one electron and one proton would not be electrically neutral due to the imbalance in charge. Instead, it would possess a net positive charge, making it a positively charged hydrogen ion.
