sorry if its wrong, i did something like this last year, and this was my answer so sorry if its wrong TwT
Hello !!
I think the answer will be is :
<h2>
B. Elements are different kinds of atoms.</h2><h2>
</h2>
Because when the atom changed it's means it's different types of the atom.
Hope It Helped!

<span>According to octet rule, atoms with an atomic number less than 20 tend to combine with other atom such that both of these atoms have eight electrons in their valence shells, which gives them the same electronic configuration as that of noble gas.
However, there are few compound that donot obey octel rule. Among the elements mentioned above i.e. oxygen and helium obeys octet rule.
In case of nitrogen, oxide of nitrogen (like NO and NO2) have incomplete octet.
While there are few compounds of Br wherein Br has expanded octet. For example, in BrF5, Br has 12 electrons in valence shell. </span>
Answer:
The particles in a solid are tightly packed and locked in place. ... The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other. The particles in a gas are fast moving and are able to spread apart from each other.
Explanation:
Answer: Option (d) is the correct answer.
Explanation:
A covalent bond is defined as the bond formed by sharing of electrons between the two chemically combining atoms.
For example, atomic number of chlorine is 17 and it has 7 valence electrons.
To attain stability it need to gain one more electron.
So, when one chlorine atom chemically combines with another chlorine atom then there occurs sharing of electrons between the two. As a result, there will be sharing of electrons.
A molecule is defined as the specie that contains same type of atoms which are chemically combined together in a fixed ratio by mass.
