Yes it’s correct.
An ionic bond is the transfer of electrons from a metal to a non-metal.
In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.
So your answer would be
C) Models help scientists visualize things they can’t see.
Answer : The magnetic moment of a single nickel atom is 
Explanation :
Formula used :
where,
= saturation magnetization = 
N = Avogadro's number = 
V = volume of nickel atom
= magnetic moment
First we have to calculate the volume of nickel atom.
Now we have to calculate the magnetic moment of a single nickel atom.
Therefore, the magnetic moment of a single nickel atom is
Answer:
Inside the bar magnet, the B is actually stronger at the centre (like in the case of a solenoid). Outside the bar magnet, B is small near the centre since there are very less open field lines there. ... A magnet has attracted iron pieces for many times your welcome XD
Explanation:
Answer:
Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface. ... The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink.
