Sodium, atomic number 11, forms an ionic bond with an atom of an unknown element. what is one possible choice for the other element in the compound?

An ionic bond is a kind of chemical bond produced via an electrostatic association between the two oppositely charged ions. Ionic bonds are produced between a cation, that is, generally a metal, and an anion, that is, generally a non-metal. A covalent bond involves a pair of electrons being shared among the atoms.

For example, consider sodium cations and chlorine anions. Sodium has a positive 1 charge and chloride has a negative 1 charge. Thus, one sodium cation cancels one chloride anion leading to the formation of NaCl.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
