Answer:
b : they move to the positive electrode
Explanation:
they lose electrons to form chlorine atoms. The atoms join up in pairs to form Cl² molecules , so chlorine gas is formed at the positive electrode
Answer:
A.) Atoms contain electrons
Explanation:
J.J. Thomson conducted an experiment in which he took a gas at low pressure in a discharge tube and applied high voltage current. When he did so, he noticed that there are some particles emitting from cathode going towards the anode. <u>Then he concluded that they are negatively charged particles and coined them electrons.</u>
<u>Hence, out of the options:- A.) Atoms contain electrons is correct.</u>
<h3><u>Answer;</u></h3>
3p34s23d7
<h3><u>Explanation</u>;</h3>
- Electrons in an atom are contained in specific energy levels that are different distances from the nucleus.
- Within each energy level is a volume of space where specific electrons are likely to be located, called orbitals. Orbitals are of different shapes, denoted by a letter (s, p, d, f, g).
- S-orbital takes a maximum of two electrons, p-orbital take a maximum of six electrons, d-orbital takes a maximum of 10 electrons, and so fourth.
- The electron filling pattern takes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p.........
- Therefore; in this case after 3p3, we then go to 4s, with 2 electrons, then 3d which takes 7 electrons.
