What is the covalent<br> bonding of calcium chloride​
algol13

Answer:

<u>Calcium chloride does not have a covalent bond , it is an ionic bond (which means donation of electrons takes place )</u>. The charge of calcium ions is +2, while the charge of sodium ions is -1. The molecule of calcium chloride contains one calcium ion (+2) and two chloride ions (-1), resulting in an overall charge of 0, or neutral.

<u>IONIC BONDING IN CALCIUM CHLORIDE</u> (CaCl_2)

Electron sharing produces covalent compounds, while electron donation produces ionic compounds. CaCl_2 is a salt with an ionic bond. This is because calcium takes up an electron to each of the chlorine atoms, resulting in Ca^2^+ions for calcium andCl^- ions for chlorine. At room temperature, it behaves like a normal ionic halide and is solid. Calcium is a metal with a non-metal sulphate bond.

<u>Thus , Calcium chloride have ionic bonds present on them . No covalent bonds takes place in calcium chloride.</u>

When comparing the two elements Br and Ga, the larger element is GaG a When comparing the two elements Br and Ga, the larger ele
dedylja [7]

Answer:

FALSE

Explanation:

Br is <em>bromine</em> with atomic number 35, mass number of 79.904 and belongs to the group 7 elements known as the halogens.

Ga is <em>gallium</em> with atomic number 31, mass number of 69.72 and belongs to the alkaline earth metal i.e the group 3 elements.

From the above and in terms of their mass number, it is evident that Br is the larger element compared to Ga which is lesser than Br. Hence the statement is FALSE
