What is huckel rule?
In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.
What does 4n plus 2indicate in uranium series?
In the uranium series, 4n + 2 represents the decay process of uranium-238 (238U) where it undergoes alpha decay to form thorium-234 (234Th) by emitting an alpha particle. The equation indicates that for every 1 decay of uranium-238, 1 thorium-234 and 2 alpha particles are produced.
What element has 2 electrons 3 protons 4 Neutrons?
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
What is the net force when you combine a force of 13N to the north and 17N to the south?
Take north to be the positive direction, and south to be the negative direction. Net force = 13N + (-17N) = -4N Net force = 4N to the south.
How many molecules are in 4n of methane?
If you think to 4 moles of methane the number is 24,088563428.10e+23.

How do you Solve 5n-2 plus 2 equals 4n?
5n-2+2=4n 5n=4n n=0
What is the value of 4n 2?
the value of 4n + 2 = 14
What is 4n-8 equals 3n plus 2?
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
What does the math term identity property mean?
In addition, the identity property means that any number plus zero is that number. For example 2+0 =2, -25 + 0 = -25, and so on. In multiplication, the identity property means that any number or variable times one equals that number. For example 5 x 1 = 5, -12 x 1 = -12, y x 1 = y, 4n x 1 = 4n, and so on.
What is the value of this expression 4n x 2?
4n x 2 = 8n
2-4N equals 2 plus 3N?
2 - 4N = 2 + 3NSubtract 2 from each side:-4N = 3NAdd 4N to each side:0 = 7NN = 0That's the only value of ' N ' for which the given equationcan become a true statement.
