Answer:

J.J Thompson

Explanation:

J.J Thompson was responsible for cathod ray experiment to determine the presence of electrons. Cathod ray tubes are easily found around us example is the cathode ray television which was used before the coming of plasma TV. cathode rays usually deposit an electric charge this can be done experimentally by putting an electrometer at the opposite end from the cathode and anode. When the cathode rays hit the electrometer, it measured an electric charge. During the experiment, he found out that charges carried by the cathode are usually negative since they move towards the positive end and away from the negative end. Using electrostatic attraction law that like charges repel, unlike charges attract, he was able to deduce that cathode rays are negatively charged.

If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of these choices shows

blsea [12.9K]

<span>Generally, a hydrogen bond can be characterized as a proton shared by two lone electron pairs. It occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.

Among the choices in the bond (-N...H-O) one side of the Hydrogen is bonded to a highly electronegative atom with a lone pair (-N) and the other side is directly bonded with a highly electronegative atom (O-).

So -N...H-O- shows a hydrogen bond.</span>

skelet666 [1.2K]

By changing the number of protons in an element, you are fundamentally changing it to a different element.

It’s worth remembering that:

Protons identify the element

Electrons determine properties and behavior of the element

Neutrons contribute to isotopes and just help keep everything stable, by separating the charges. Remember opposites attract. Like charges repel.
