jeka94

Answer:

Discovery of electron while studying the properties of cathode ray by Thomson suggested that Dalton atomic model should be revised.

Explanation:

Electron was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.

Properties of cathode ray:

The ray is travel in straight line.

The cathode ray is independent of composition of cathode.

When electric field is applied cathode ray is deflected towards the positively charged plate.

Hence it was consist of negatively charged particles.

Symbol= e-

Mass= 9.10938356×10-31 Kg

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

Hey there! Here are 10 fun facts to brighten your day!

1. Three presidents, all Founding Fathers—John Adams, Thomas Jefferson, and James Monroe—died on July 4. Presidents Adams and Jefferson also died the same year, 1826; President Monroe died in 1831. Coincidence? You decide.

2. The Barbie doll’s full name is Barbara Millicent Roberts, from Willows, Wisconsin. Her birthday is March 9, 1959, when she was first displayed at the New York Toy Fair.

3. There actually aren’t “57 varieties” of Heinz ketchup, and never were. Company founder H.J. Heinz thought his product should have a number, and he liked 57. Hint: Hit the glass bottle on the “57,” not the bottom, to get the ketchup to flow.

4. One of President John Tyler’s grandsons is still alive today—and he was born in 1790. How is this possible? President Tyler, the 10th US president, was 63 when his son Lyon Tyler was born in 1853; Lyon’s son was born when he was 75. President Tyler’s living grandson, Harrison Tyler is 92. Lyon’s other son Lyon Jr. passed away in 2020 at the age of 95. The Tyler family still maintains the President’s home, Sherwood Forest Plantation in Virginia.

5. The tallest man ever recorded was American giant Robert Wadlow (1918–1940), who stood 8 feet 11 inches. Wadlow’s size was the result of an abnormally enlarged pituitary gland.

6. The oldest person ever to have lived (whose age could be authenticated), a French woman named Jeanne Louise Calment, was 122 years old when she died in 1997.

7. Sliced bread was first manufactured by machine and sold in the 1920s by the Chillicothe Baking Company in Missouri. It was the greatest thing since…unsliced bread?

8. The Earl of Sandwich, John Montagu, who lived in the 1700s, reportedly invented the sandwich so he wouldn’t have to leave his gambling table to eat.

9. The first college football game was played on November 6, 1869, between Rutgers and Princeton (then known as the College of New Jersey) in New Brunswick, New Jersey. Rutgers won.

10. Experiments in universities have actually been carried out to figure out how many licks it takes to get to the center of a Tootsie Pop, both with the machine and human lickers (because this is important scientific knowledge!). The results ranged from 252 to 411.
