What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
Why was the plum pudding model of the atom not successful?
There are a few reasons why Thomson's atomic model failed. It did not consider the reasoning behind atomic reactions or neutrality. It was just a visual he created with electrons placed haphazardly on a proton base. That arrangement is why it is commonly known as the plum pudding or raisin bun model.
By what criteria are the planets placed into either the Jovian or terrestrial group?
Planets are either earth-like or Jupiter-like.
What happened to the bears when placed in distilled water?
It expands. Get bigger over a period of time.
Why are negatively charged amino acids acidic?
Negatively charged amino acids are acidic bacause they gave a proton (H+) to the solution. The amino acid was not charged before it went into the solution, but lost a hydrogen when placed in water and became negativley charged. It also donated a proton to the solution so it is considered acidic. Similar logic applies with the basic amino acids.
What happens when a charged particle is placed in the electric field of another particles with the same charge?
they either attract or repel
What happens when a charged particle is placed in the electric field of another particle with the same charge?
they either attract or repel
What is a Cathode ray gun?
basically JJ Thomson wanted to find out what a cathode ray was made of. Cathode tubes are a tube with wires in them. Scientists discovered that if the created a vacuum in the tube and sent a charge through the wires, it glowed. JJ Thomson set up a cathode ray and placed magnets on either side. This deflected the ray so the tube didn't glow. This meant the rays were negatively charged which meant they were made of negatively charged particles or electrons.
What happened to the butter when placed under the sun why do you think this happened?
When butter is placed under the sun, it will melt.
What observations did Thomson make to suggest that an electron has negative electric charge?
Thomson observed that a cathode ray bent when in the presence of a magnetic field. After the cathode ray bent the opposite way when the opposite pole of the magnet was placed next to it, Thomson concluded that the cathode ray had a negative charge.
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
What happens when a negatively charged object is placed near another negatively charged object?
They scoot away from each other
What happens when charged objects placed near the neutral objects?
There will be an attractive interaction between the charged object and the neutral object.
Does salt release positively charged hydrogen ions when placed in water?
No.
What happens when two positively charged material is placed together?
The material will
What is polarising?
When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.
What is charged affairs?
Someone placed in a position of responsibility for a certain set of matters.
