Aluminium reacts with the acidic content of mango pickle, leading to the formation of harmful compounds.
Aluminium reacts with the acidic content of mango pickle
This reaction can lead to the formation of harmful compounds
These compounds can contaminate the pickle and make it unsafe for consumption
- Q7. Ifan element x keep on period 14 what will be its structure
- Ans.
The structure of an element in period 14 depends on its atomic number and electron configuration.
Elements in period 14 can have various structures depending on their atomic number.
The structure can be determined by the electron configuration of the element.
For example, if element X has an atomic number of 57, its structure would be [Xe] 4f^14 5d^1 6s^2.
- Q8. Group 17 elements also known as what
- Ans.
Group 17 elements are also known as halogens.
