Who is the father of modern science? Galileo Galilei Who was the first woman chemist? When it comes to the topic of women in science, Marie Curie usually dominates the conversation. After all, she discovered two elements, was the first women to win a Nobel Prize, in 1903, and was the first person to win […]
Do elements in Group 1 gain or lose electrons?
Do elements in Group 1 gain or lose electrons? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions. Most elements in […]

Can sound waves bend?
Can sound waves bend? Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not “see” a target that would ordinarily be well within sonar range. The other example is the difference in how well sound carries up/down wind. What is […]
What is the two main function of a diode?
What is the two main function of a diode? Main functions The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version […]
Why are batteries called AA?
Why are batteries called AA? But the most significant difference is size because batteries are called AA & AAA because of their size and dimension. AA doesn’t stand for anything. It is simply an identifier for a battery of given dimensions and nominal voltage. Are C batteries the same as AA? AA batteries are the […]
