Calcium chloride contains only calcium and chloride. What is the formula for this compound

Answers

Answer 1

Answer: Calcium give the cation $Ca^(2+)$ , chloride gives the anion $Cl^-$ . The compound is electrically neutral, and is hence $\boxed{CaCl_2}$

Answer 2

Answer:

Answer:

B.) CaCl2

Explanation:

CaCl2 Calcium has a positive 2 charge and chlorine has a negative 1 charge. It takes 2 chlorine atoms for every calcium in order to be neutral.

Which atomic model was proposed as a result of J. J. Thomson’s work? the plum pudding model the indivisible atom model an atom that had a lot of empty space an atom that had a concentrated nucleus

Answers

J. J. Thomson worked in the field of chemistry and proposed the atomic model theory after the discovery of the electron. He proposed the plum pudding model. Thus, option A is correct.

What is the plum pudding model of the atom?

The plum pudding model of the atom was proposed by J.J. Thomson, after the discovery of electrons. The “plum pudding” atomic model was based on the plum cake structure where the sub-atomic particles were placed.

According to the model, the electrons being negative species were embedded as the cherries in the structure, while the protons being positive in charge were freely present in the rest of the pudding.

Therefore, Thomson proposed the “plum-pudding” atomic model.
