Matter is anything that is made up of atoms. The matter word is mainly used in science. Therefore Option C are correct option.
Matter is a substance that has some mass and can occupy some volume. . Matter can be solid, liquid or gas.
In case of solid, particles are fixed at its mean position, they do not move at all. In gas, particles move very fast. They do not remain at its mean position. They continuously keep on moving with high kineticenergy called Brownian motion. In liquid particles are moveable, they are neither very stiff nor they move very fast. There is surface tension between the particles and the layers of liquid. Therefore, the layers of liquid just slide around each other. And this property of liquid is the reason for its fluidity.
Thus option c is correct option

nonmetals
Answer:
Nonmetals typically combine to form covalent compounds.
Explanation:
The octet rule states that the atoms of the elements bond each other in the attempt to complete their valence layer with eight electrons. That is to say, the atoms will tend to yield or share electrons to complete eight electrons in the valence layer.
In other words, the objective is to have the closest noble gas electronic configuration, thus having the last complete electron layer and acquiring stability.
The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons at their outermost level (valence electrons) and tend to gain electrons in order to comply with the octet rule mentioned and be stable. The shared electron pair is common to the two atoms and holds them together.
Then, nonmetals typically combine to form covalent compounds.
Answer: ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.
