10. What was robert millikan's contribution to the atomic theory?

Question :

What was robert millikan's contribution to the atomic theory?

Answer :

first direct and the electric charge of a single electron

11. Date: April 11, 2023 Most Essential Learning Competency (MELC) TOPIC SCIENCE 7 INTERVENTION Learning Task A. Reading Selection Electricity may be described as a form of energy. Understanding electricity entails understanding charges - the basic unit of electricity. Charge is a quantity measured in Coulombs (C). Charges may be transferred to and from objects and may move in conductors as current measured in Amperes (I). The world we live in is highly dependent on the electric energy and power (measured in Watts) supplied by our power plants. The unit watt (W) is named to honor James Watt, the inventor of the steam engine during the industrial revolution. Electric charge is an intrinsic property of protons and electrons. Charge is a quantity with a magnitude and unit. The SI unit of charge is the Coulomb (C). A neutron has zero net electrical charge because it is neutral A proton carries a positive charge (+e), while electron carries a negative charge (-e). These two types of charges (positive and negative) were named by Benjamin Franklin. JJ. Thomson discovered the electron an Robert Millikan discovered the charge of the electron. The charge of the electron is the negative of the elementary charge e which is equal to 1.6 x 10-19 Coulomb. The charge of the electron and the proton are the same only that the proton is positive (+1.6 x 10-19 Coulomb). Like sign of charges repel and unlike sign of charges attract each other. Materials may contain several charges and when these are neutral, they contain equal numbers of positive and negative charges. Materials or bodies may be left with a certain charge. This may be done through the process of charging. charging means gaining or losing electrons. There are various types of charging processes namely, charging by friction, charging by conduction, and charging by induction. Let us describe first the process of charging through friction. Guide Questions: 1. What is the charge of a neutron? 2. Who discovered the electron? Describe the different types of charging processes (MELC 21) Electricity There are many different types of atoms, and these atoms can combine in a variety of ways to form the nature of objects we encounter every day. Depending on the type of atoms an object is made of, an object can be more or less attracted to an electron. This electrical property is known as electron affinity. If an object has a high electron affinity, then it is more attractive to electrons. Different materials have different affinities of electrons. This is important as we explore the most common methods of charging-triboelectri charging, also known as charging by friction or rubbing. 3. Who invented the steam engine? 4. What is electron affinity? 5. What is electricity? 6. What is current? 7. What is the unit of power? 8. What is the charge? 9. What is triboelectric charging? 10. How can materials be charged?​

Answer:

1. The charge of a neutron is zero (0).

2. The electron was discovered by JJ Thomson.

3. James Watt invented the steam engine.

4. Electron affinity is the electrical property of an object that determines its attraction to electrons.

5. Electricity may be described as a form of energy that involves charges - the basic unit of electricity.

6.Current is the flow of electric charge measured in Amperes (I).

7.The unit of power is Watt (W).

8. Charge is a quantity with a magnitude and unit. The SI unit of charge is Coulomb (C).

9. Triboelectric charging is the process of charging by friction or rubbing.

10. Materials can be charged through various processes such as charging by friction, charging by conduction, and charging by induction.

28. Robert millikan atomic theory contribution

Answer:

His earliest major success was the accurate determination of the charge carried by an electron, using the elegant “falling-drop method”; he also proved that this quantity was a constant for all electrons (1910), thus demonstrating the atomic structure of electricit
