Answer:
C Which model is composed of electrically charged particles?
Explanation:
The best question to resolve and determine the model which is plasma is to find one that is composed of electrically charged particles.
Plasma is one of the states of matter which is characterized by ions and other charged particles.
Matter is anything that has weight and occupies space.
There are four known states of matter which are:
Plasma is the only state of matter made up of charged particles.

Long story short, C is the answer.
The correct answer is A) They all have similar chemical properties.
Explanation:
In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.
These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".
Each set of elements has an equal number of electrons in the outer orbital. We refer to these as valence electrons. Each element's chemical characteristics are determined by its valence electrons. The correct option is A.
The elements in the same group or column of the periodic table are those whose chemical characteristics are the most comparable. The vertical groups of elements that have the same number of valence electrons and, consequently, comparable chemical characteristics are formed when the elements are arranged in order of atomic number.
Only when matter changes to become a completely other sort of matter can chemical characteristics be measured or observed. They consist of flammability, reactivity, and rusting potential.
Thus the correct option is A.
