Answer:
The diagram is incorrect because there is only a single type of particle at the center of the atom.
Explanation:
The small circle at the centre of the sphere which contains six light gray spheres and six dark gray spheres represents the nucleus of the atom which is found at the centre of the atom.
The nucleus contains only one type of particle which is the proton. Hence the representation of two particles at the centre of the circle makes the model incorrect.
Atoms are the smallest form of the substance. examples of atoms are in elemental forms such as copper, helium, silver. Diatomic molecules are made up of identical atoms. Examples are I2.. F2 and Br2. Formula units are those compounds that are made up of two or more elements such as -No2, KMnO4,<span>C3H8, MgCl2, HgBr2, Ba(OH)2</span>
<u>Given:</u>
Diameter of a red blood cell = 0.000008
<u>To determine:</u>
The scientific notation corresponding to the given number
<u>Explanation:</u>
Scientific notation is a concise way of representing a very large or small number. It is written in two parts:
Given Number = Digits * Power of 10
In this case we have:
0.000008 = 8.0 * 10⁻⁶
