The atomic number of the atom is 13. This means that its electronic configuration is (2 8 3) or in other words:
1<span>s2, </span>2<span>s2, </span>2<span>p6, </span>3<span>s2, </span>3<span>p<span>1
If three electrons are lost, then these electrons are removed from the outermost level.
In our case, electrons are removed from the third energy level (one electron is removed from the 3p orbital and two electrons are removed from the 3s orbital).</span></span>
Answer:
Explanation:
Essential Knowledge
It is essential that the student be able to distinguish between specialized structures that allow protists and fungi to obtain energy and explore their environment.
Protists
Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics.
● Protists are usually single celled organisms.
● Live in moist environments.
● Vary in the ways they move and obtain energy.
Protists obtain their energy in several ways.
● Animal-like protists ingest or absorb food after capturing or trapping it.
● Plant-like protists produce food through photosynthesis.
● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites.
● Some protists have both autotrophic and heterotrophic characteristi

<u> Answers</u>
1. precision
2. density
3. control
4. matter
5. accuracy
6. gradation
<u>Explanation</u>
1. An indication of how close a measurement is to the correct result is called precision.
2. The mass of a substance per unit volume is called density of a substance.
3. A quantity in an experiment that remains unchanged or constant is called a control group.
4. Anything that has mass and occupies space is called matter.
5. The degree to which a measurement can be replicated is called accuracy.
6. Scale markings that denote equal units of measure is called gradation.
