In 1820, the British scientist William Thomson (later known as Lord Kelvin) made a momentous call that revolutionized the field of electricity:
Thomson was experimenting with static electricity and discovered that when a current flowed through a wire, it deflected a magnetic needle. This phenomenon, known as electromagnetism, was a groundbreaking discovery.
I took a hollow tube of wire, and passing an electric current through it, I found that the needle of a magnet which was close to the tube was deflected. The degree of deflection was proportional to the strength of the current.”
Thomson’s first call was a pivotal moment in history that paved the way for countless technological advancements and scientific breakthroughs. It is a testament to the power of discovery and the enduring legacy of scientific curiosity.
What was Thomson’s first model of the atom?
Thomson’s first model of the atom, known as the “plum pudding model,” proposed that the atom was a sphere of positive charge with negatively charged electrons embedded within it, like plums in a pudding. This model suggested that the positive and negative charges were uniformly distributed throughout the atom.
What is the model of Thomson theory?
The Thomson theory, or the plum pudding model, described the atom as a positively charged sphere with negatively charged electrons scattered within it. This model was developed after Thomson discovered the electron in 1897 and attempted to explain how these negatively charged particles could exist within a positively charged atom.
What was the first model of the atom?
The first model of the atom was proposed by J.J. Thomson and is known as the “plum pudding model.” Prior to this, the atom was thought to be indivisible. Thomson’s model introduced the idea that atoms consisted of smaller, negatively charged electrons within a positively charged matrix.
Which model was discovered by J.J. Thomson?
J.J. Thomson discovered the “plum pudding model” of the atom. This model was his hypothesis for the atomic structure after discovering the electron, suggesting that atoms were not indivisible and contained subatomic particles.
