What is the trem for an atom with an unequal number of protons an electrons?

An atom with an unequal number of protons and electrons is referred to as an ion. If it has more protons than electrons, it is called a cation and carries a positive charge. Conversely, if it has more electrons than protons, it is known as an anion and carries a negative charge.


What trem is defined as all the population of various species interacting in a given area?

The term that describes all the populations of various species interacting in a given area is "community." In ecological terms, a community encompasses the different plants, animals, fungi, and microorganisms that coexist and interact within a specific environment. These interactions can include competition, predation, and symbiosis, all of which play a crucial role in shaping the ecosystem.


Which trem describes the sum of the number of protons and neutrons in an atom?

"Atomic mass" is the sum of the number of protons and neutrons in the nucleus of the atom. All atoms of an element have the same number of protons. For example, all iron atoms have 26 protons. But while most (90%) have 30 neutrons, there are isotopes of iron that have anywhere from 26 to 36 neutrons. So the published "atomic mass" is the weighted average of the combined number of protons and neutrons. That's why the atomic number is always a whole number, but the atomic mass is a decimal.


How would you define the trem biodiversity?

Biodiversityis the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function ofclimate. In terrestrial habitats, tropical regions are typically rich whereas polar regions support fewer species.
