Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2
The effect is due to static electricity when Lucas rubbed plastic ruler on the sweater he caused the ruler to become negatively charged due to rubbing creating a negative charge that is carried by electrons so when he waved above pieces of paper positive charges present in the atoms of paper became attracted to negatively charged ruler.

Answer:
Please find the correctly matched terms with their definition below:
Explanation:
1. Binomial nomenclature: As the name implies i.e. Binomial meaning"two", binomial nomenclature is the two-name system of naming living things used in classification.
2. Biosphere: Biosphere refers to all life on Earth including plants, animals, microbes etc.
3. Class: Class is one of the seven levels of classification, which is a taxonomic category containing a group of similar orders.
4. Phylum: Phylum is also a level of classification used majorly for classifying plants. In plant classification, It is a group of similar classes.
5. International Code of Nomenclature: Abbreviated as IUCN, it is an elaborate set of rules for naming organisms in taxonomy.
6. Kingdom: Kingdom is the least specific taxon. Kingdom represents the largest taxonomic category containing most organisms.
7. Order: Another level of classification that describes a taxonomic category containing a group of similar families.
8. Division: Division is a taxon used instead of phylum when a plant is not involved. In classification (other than plant), phylum is a grouping of similar classes.
9. Taxon: Taxon refers to the categories used in classifying plants and animals.
