Which of the following is not a correct formula? A)Ba2O B)Ca3N2 C)KCl D)Li2S
love history [14]

Answer:- A. Ba_2O is not the correct formula.

Explanations:- Charge for Ba is +2 and charge for O is -2, Here the charges are in equal and opposite so their ratio is 1:1 and hence the formula must be BaO and not Ba_2O.

Rest of the formulas are correct as charge for Ca is +2 and charge for N is -3 . On criss cross we get the formula Ca_3N_2 .

Charge for K is +1 and charge for Cl is -1 and so KCl is correct.

Charge for Li is +1 and that for S is -2. On criss cross we get the formula Li_2S .

Which of the following observations indicates that atoms of all elements contain small, negatively charged particles? Alpha part
Marizza181 [45]

Answer:

The correct option is;

Cathode rays are deflected towards a positively charged rod

Explanation:

Cathode rays are  beam of electrons emitted from the cathode in a vacuum tube and moving towards the anode, due to the difference in the voltage between the electrodes

The discovery of the electrons was through the proof by Thomson that cathode rays were a negatively charged, previously unknown particle, which was to become known as the electron.
