Alkali metals will always contain one valence electron but the electron configuration will depend on the element
Answer:
(a)
(b) The particles of the formed barium sulfate remain suspended in the aqueous media forming a colloid.
Explanation:
Hello,
In this case, when solutions of barium chloride and sodium sulfate are mixed, the following chemical reaction is carried out:
Thus, we can notice that the product barium sulfate remains solid since its solubility in aqueous media is very low, for that reason at the beginning the solution becomes cloudy as its particles remain suspended in the water forming a colloid. Nevertheless, after some days, the suspended particles get precipitated by the effect of the gravity, therefore, we observe the solid on the bottom of the beaker.
Regards.

Explanation:
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>
Electron sharing produces covalent compounds, while electron donation produces ionic compounds. is a salt with an ionic bond. This is because calcium takes up an electron to each of the chlorine atoms, resulting in ions for calcium and 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>
Electrical energy is the energy of electrons
