The correct answer is Neutron
Explanation:
As shown in the diagram the sub-particles in atoms are electrons, neutrons, and protons. From these, the two types of particles that are in the nucleus or center of the atom are neutrons and protons. Moreover, neutrons differ from protons because these are neutral or are not charged. According to this, the uncharged particles in atoms are neutrons.
Moreover, the number of neutrons can be calculated by subtracting the atomic number (number of protons) to the mass number (number of atoms and protons). For example, if in an atom the mass number is 12 (protons and neutrons)and the atomic number is 6 (number of protons), the neutrons are 6 (12 - 6 = 6). According to this, the correct answer is the neutron.
A scoring rubric is an attempt to communicate expectations of quality around a task. In many cases, scoring rubrics are used to delineate consistent criteria for grading.

The mode for this set of data is: 45.
<h3>What is mode?</h3>
Mode can be defined as the number that appear more than other numbers.
The given chart is:
Anxious behaviors per hour
Subject 1 60
Subject 2 45
Subject 3 20
Subject 4 70
Subject 5 45
Based on the above chart we can see 45 in subject 2 and 45 in subject 5 which in turn means that 45 appear more than others numbers as it appear twice.
Therefore The mode for this set of data is: 45.
