Answer:
metallic bonding is the bond form between two or more metal elements or between metal element and the other group elements
Answer:
They are both halogens and have the same number of electrons on their outer shell.
Any element with 7 electrons in the outermost shell will have similar properties. Thus other elements in the same column of the periodic table as chlorine will have similar properties.

Answer: The mass of air present in the room is 37.068 kg
Explanation : Given,
Length of the room = 10.0 ft
Breadth of the room = 11.0 ft
Height of the room = 10.0 ft
To calculate the volume of the room by using the formula of volume of cuboid, we use the equation:
where,
V = volume of the room
l = length of the room
b = breadth of the room
h = height of of the room
Putting values in above equation, we get:
Conversion used : 
Now we have to calculate the mass of air in the room.
Conversion used : (1 kg = 1000 g)
Therefore, the mass of air present in the room is 37.068 kg
Answer:
D. Thermal conduction is blocked by the flip-flops.
Explanation:
Convection is a process of heat transfer which involves fluids( liquid or gas). This however rules convection out of the answer.
Radiation involves heat transfer from the sun to bodies on earth.
Conduction involves heat transfer between two solid bodies. Hot beach sand and flip-flops are solid bodies which validates thermal(heat) conduction.
