Answer:
the atom
Explanation:
The bread and cheese separately represent the atom because both bread and cheese are different from one another and we cannot assume it as a molecule because molecules formed when the group of atoms combine together by making bonds with each other and we know that bread and cheese did not make bonds with each other, they only attached, so we called them atoms not molecule.
Explanation:
Methane (CH₄)
Valence electrons of carbon = 4
Valence electrons of hydrogen = 1
The total number of the valence electrons = 4 + 4(1) = 8
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
<u>The Lewis structure is:
</u>
H
:
H : C : H
:
H
A model of an atom is important in the understanding of the properties of all the objects around us. We can identify whether a specific material is iron or gold or anything else. Due to the model of an atom we can characterize each element. Elements in the same group would show similar chemical and physical properties present. This is because those elements have similar electronic configuration and we know this due to the atomic model. Also, it helps us to have an idea on how to synthesize certain substances so we can just produce them rather than obtaining it from natural means. With a better understanding of an atom, we can better understand chemical principles.
