Electronegativity decreases as you go down a colum in the periodic table.
The answer is actually A, 1s 2s 2p 3s 3p 4s 3d 4p.
They are gases at room temperature
Hope this helps:)
Answer:
B
Explanation:
Trust me I've had problems like these
Explanation:
Both conduction and convection are both forms of heat transfer from one place to another.
- In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
- Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
- Heat transfer in conduction is quite slow compared to convection which is much faster.
Example of conduction is heating of iron pot when cooking
Example of convection is the refrigerating system.
