Why do Group 7 elements have 7 valence electrons? Group 7 elements are also called halogens. Halogens all have 7 valence electrons, meaning they only require 1 more electron to reach the desired 8 in the valence. Since they only require 1 more electron, the halogens are quite reactive. How many valence electrons does group […]

What is the function of magnetic field?
What is the function of magnetic field? Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. The use of magnetic fields to generate electric current. What is […]
Is wearing a magnet bad for your heart?
Is wearing a magnet bad for your heart? Because blood conducts electricity, its flow through the very powerful magnetic field generates a current. But there seems to be no indication of any damage to the heart. Can magnets damage eyes? As with magnetic liner, it’s possible to have an allergic reaction to magnetic eyelashes. You […]
What does the slope and y intercept represent?
What does the slope and y intercept represent? The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0. What does slope mean in real […]
What does 10X magnification mean?
What does 10X magnification mean? A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size. Compound microscopes use two or more lenses to magnify the specimen. The standard school microscope combines two lenses, the ocular and one objective lens, to magnify […]
How can you tell the difference between polar and nonpolar molecules?
How can you tell the difference between polar and nonpolar molecules? Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. What does it mean when […]

Why is stormwater runoff bad?
Why is stormwater runoff bad? Why is stormwater pollution so bad? As polluted water makes its way to the oceans, water quality can be affected, which often results in the closing of local beaches due to unhealthy water conditions. Stormwater carries disease-causing bacteria and viruses. Swimming in polluted waters can make you sick. Why is […]
