That type of bending is called "diffraction" of waves.
Lithium is to be considered as an ION
Atom is defined as its natural state where it will have all its electrons present in its shell
Since in this case Lithium is giving its electron so after giving the electron it will become an ion
Compound is the combination of two or more different atoms
Molecules is the combination of same type of atoms
So here answer must be
<em>C) ion</em>
Answer:

Explanation:
From frequency of oscillation

Initially with the suspended string, the above equation is correct for the relation, hence

where k is force constant and m is the mass
When the spring is cut into half, by physics, the force constant will be doubled as they are inversely proportional

Employing f2/ f1, we have

Making models
is a skill that involves creating a representation of complex objects or
processes. Through the years, people have been creating models in order to
make a clearer visualization and give reality to a certain object. Some
example of model making are toys like plastic cars as a model
representation of a real car, a plastic plane, model representation of a
real plane and a doll, a model representation of us, human. One of the
most famous model representation as of today is the film or movie making.
This represents the lives of the people and show stories about how people
face every challenge in life.
