Why do electrons want to be stable? A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. A stable arrangement is attended when the atom is […]

Can magnetic fields interact with each other?
Can magnetic fields interact with each other? When two magnets are brought close together, their magnetic fields interact. You can see how they interact in the Figure below. The lines of force of north and south poles attract each other whereas those of two north poles repel each other. When electric and magnetic fields both […]
How much energy does it take to remove an electron from magnesium?
How much energy does it take to remove an electron from magnesium? Magnesium has the electron configuration of 1s22s22p63s2. The first two electrons are removed from the third level. The third electron is removed from the second level. Electrons in lower levels feel a greater attraction to the nucleus and are more difficult to remove….Ionization […]
Can a Boeing 747 break the sound barrier?
Can a Boeing 747 break the sound barrier? As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which […]
What are the 3 blood vessels?
What are the 3 blood vessels? An adult’s would be closer to 100,000 miles long. There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. How many blood vessels are attached to the heart? […]
What is Catenation explain with reference to group 14?
What is Catenation explain with reference to group 14? The property of self-linking of atoms of an element through covalent bonds to form straight or branched chains and rings of different sizes is called catenation. Amongst the group 14 elements, C-C bond strength (355 kJ mol1) is maximum, therefore, carbon shows maximum tendency for catenation. […]
