What happens to a potassium atoms electrons when it becomes an ion?

Scrat [10]

The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.

AysviL [449]

Answer:

An individual can be placed or classified into a particular species depending on the concept a scientist has considered,

The three most prominent are Biological, morphological and phylogenetic species concept.

1. Biological species concept- Individuals that can interbreed naturally are placed into the same species. Therefore, Biological species concept, not applicable for extinct species

2. Morphological - Relies on similarities in structure

This species concept places individuals having similar body structures into the same species. It can be easily applied to asexual and extinct species.

3. Phylogenetic - Based on evolutionary history

Species are classified according to a common ancestor.

4. Morphological and Phylogenetic

Accommodates asexual reproduction

Species acceptance criteria can be subjective

5. Morphological, Phylogenetic, and Biological

Used by scientists in classification

All the three concepts are used for classification.
