According to the valence bond theory, Electrons in a molecule occupy atomic orbitals rather than molecular orbitals. The atomic orbitals overlap on the bond formation and the larger the overlap the stronger the bond.
The metal bonding is essentially covalent in origin and metallic structure involves resonance of electron-pair bonds between each atom and its neighbors.

Cells are the basic, fundamental unit of life. So, if we were to break apart an organism to the cellular level, the smallest independent component that we would find would be the cell.

The communication cycle expresses how the system of conveying and understanding messages operates.
Different depictions of the cycle may include slightly different steps and descriptions, but most agree on the basic elements:
- Sender: the person or entity originating the communication
- Message: the information that the sender wishes to convey
- Encoding: how the sender chooses to bring the message into a form appropriate for sending
- Channel: the means by which the message is sent
- Receiver: the person or entity to whom the message is sent
- Decoding: how the receiver interprets and understands the message
- Feedback: the receiver's response to the message

TEP DEVIATION METHOD:
Step deviation method is used in the cases where the deviation from the assumed mean 'A' are multiples of a common number. If the values of ‘di’ for each class is a multiple of ‘h’ the calculation become simpler by taking ui= di/h = (xi - A )/h
Here, h is the class size of each class interval.
★★ Find the class marks of class interval. These class marks would serve as the representative of whole class and are represented by xi.
★★ Class marks (xi) = ( lower limit + upper limit) /2
★★ We may take Assumed mean 'A’ to be that xi which lies in the middle of x1 ,x2 …..xn
MEAN = A + h ×(Σfiui /Σfi) , where ui = (xi - A )/h
[‘Σ’ Sigma means ‘summation’ ]
FREQUENCY DISTRIBUTION TABLE
★★ Here,the frequency table is given in inclusive form. So we first change it into exclusive form by subtracting and adding h/2 to the lower and upper limits respectively of each class ,where ‘h’ denotes the difference of lower limit of a class and upper limit of the previous class.
Here, h/2 = ½ = 0.5
From the table : Σfiui = 25 , Σfi = 400
Let the assumed mean, A = 57, h = 3
MEAN = A + h ×(Σfiui /Σfi)
Mean = 57 + 3 (25/400)
= 57 + 3 (1/16)
= 57 + 3/16
= 57 + 0.187
= 57.187
Mean = 57.19 (approximate)
Hence, the Mean number of mangoes kept in a packing box is 57.19 (approximate)
