ionic bonding.
Ionic bonding<span> is a type of </span>chemical bond<span> that involves the </span>electrostatic attraction<span> between oppositely charged </span>ions<span>, and is the primary interaction occurring in </span>ionic compounds<span>. The ions are atoms that have gained one or more </span>electrons<span> (known as </span>anions<span>, which are negatively charged) and atoms that have lost one or more electrons (known as </span>cations<span>, which are positively charged). This transfer of electrons is known as </span>electrovalence<span> in contrast to </span>covalence<span>. In the simplest case, the cation is a </span>metal<span> atom and the anion is a </span>nonmetal<span> atom, but these ions can be of a more complex nature, e.g. molecular ions like NH</span>4+<span> or SO</span>42−<span>. In simpler words, an ionic bond is the transfer of electrons from a </span>metal<span> to a </span>non-metal<span> in order to obtain a full valence shell for both atoms.</span>
I believe the correct answer is the second option. Monocots and dicots are two groups of angiosperms. This group of plants are seed bearing plants. Flowers are their reproductive system where the ovules are being enclosed in the ovary. Angiosperms can be found in every habitat from grasslands and forests to deserts and sea margins. Angiospersms are divided to monocots and dicots. Monocot plants are characterized by having one cotyledon while dicots have two. Also, leaf veins of monocots are branched while that of dicots are parallel. The root system of monocots is a fibrous root system while dicots have a taproot system.
