Define effective nuclear charge

Answer» The effective nuclear charge is the net charge an electron experiences in an atom with multiple electrons.Higher energy electrons can have other lower energy electrons between the electron and the nucleus, effectively lowering the positive charge experienced by the high energy electron.Examples: A 2s lithium electron can have 2 1s electrons between itself and the lithium nucleus. Measurements indicate the effective nuclear charge experienced by a 2s lithium electron is 0.43 times the charge of the lithium nucleus.

What is difference between magnification and linear magnification

Answer» The\xa0difference\xa0is that of measure;\xa0linear\xa0magnification\xa0is used when projecting an image on a screen and\xa0angular\xa0when viewing through an eyepiece. Linear\xa0Magnification\xa0is the ratio of the projected image size (measured with a ruler) over the actual size. Angular\xa0magnification\xa0is the ratio of the tangent of the angle subtended at the focal point of the eyepiece over the angle subtended at the focal point of the objective.\xa0Linear\xa0is clear and easy - but you cannot do a\xa0linear\xa0calcuation for a\xa0magnification\xa0system with an eyepiece as there is no screen so we use the ratio of the angles (or their tan) instead as this can be observed. If something without\xa0magnification\xa0covers 1 degree - with 5x\xa0Angular\xa0magnification\xa0it will appear to cover ~5 degrees (at low mag and angles you can almost ignore the tangent).

Why should a magnisium ribbon be cleaned before burning in air

Answer» By rubbing it with sand paper which removes the oxide layer of magnesium
Because the oxyen is present on it so it can take more time to burn but if we clean with sand paper before burning
Becaz it gets reacted with oxygen present in the air and becomes magnesium oxide
Magnesium is very reactive element. When stored , it react with oxygen and a layer of magnesium oxide on its surface and protect magnesium from further reaction with oxygen. Thus magnesium ribbon is cleaned before burning in air to remove this layer.
