1. The atomic number of an atom is the number of protons in the nucleus.

2. An ion is an atom that has an unequal number of protons and electrons.

3. Photosynthesis occurs in the chloroplasts; respiration occurs in the mitochondria.

The electron configuration of alkali metals would then resemble those of group 17 of the periodic table in the compounds they form.

<h3></h3><h3>What is periodic table?</h3>

Periodic table is defined as a tabular approach of showing the items so that they appear in the same vertical column or group when their attributes are similar. Phosphorus is the oldest chemical element, and hassium is the newest. Please take note that, unlike in the Periodic system, the elements do not exhibit their natural relationships with one another.

The elements that make up group 17 of the periodic table are the halogens. They are nonmetals that are reactive, such as iodine, bromine, chlorine, and fluorine. Halogens are non-metals that are very reactive. These substances share a lot of characteristics with one another.

Thus, the electron configuration of alkali metals would then resemble those of group 17 of the periodic table in the compounds they form.

(a)kcl ionic (b)p4 nonpolar covalent (c)bf3 nonpolar covalent (d)so2 nonpolar covalent (e)br2 nonpolar covalent (f)no2 nonpolar
Angelina_Jolie [31]

Because K and Cl have such a large disparity in their electronegativities, KCl is a bipolar ionic molecule.

<h3>What exactly are polar and nonpolar bonds?</h3>

Polar covalent bonds develop when the distribution of electrons among atoms is uneven, whereas nonpolar side chains develop when the distribution of electrons is more even. The reason for the unequal sharing of electrons is because the atoms receiving them have various electronegativities.

<h3>How are polar bonds created?</h3>

Whenever a single pair of electrons is not shared equally, a polar molecule bond is created. This is caused by the electronegativity difference between the two elements. An unit of h as well as an unit of bromine share a pair of electrons, but not evenly.
