- Explain electronegativity? and how it can justify why a . . . - Socratic
An old story "Electronegativity" is conceived to be the ability of an atom involved in a chemical bond, to polarize electron density towards itself See here; and here; and here Metals TEND to be electron-rich and donate electrons On the other hand, non-metals, have high nuclear charges, and tend to attract electrons in their compounds Oxygen and fluorine are the MOST electronegative
- How do electrons fill orbitals? - Socratic
1s orbital has least energy because it has lowest n+l value, 2s orbital has greater energy than 1s because its n+ l value is 2 which is more than n+l value for 1s orbital
- So whenever am expressing atom in it hybridization should I . . . - Socratic
A single valence electron structure cannot represent it A "hybrid" structure is an "average" picture of different atomic states It can be shown as the equilibrium between states of valence electrons, but a single valence electron structure cannot represent it In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where

- Question #0cc70 - Socratic
1 * 10^(26) "protons" For starters, you know that chlorine has an atomic number equal to 17, which implies that every atom of chlorine, "Cl", has 7 protons in the nucleus Consequently, you can say that every chlorine molecule, "Cl"_2, which contains two atoms of chlorine, will have a total of 34 protons All you have to do now is to figure out how many molecules of chlorine are present in

- Question #cd77d - Socratic
The Periodic Table of the Elements arranges the elements in columns of similar valence electrons, which are the electrons involved in chemical reactions Thus, any element in the same column as another element will have similar valence electron structure, and therefore similar chemical reactivity
- Trigonometric Form of Complex Numbers - Socratic
What is DeMoivre's theorem? How do you find a trigonometric form of a complex number? Why do you need to find the trigonometric form of a complex number? Why is a number raised to a negative power the reciprocal of that number? How do you simplify # [2 (cos 135degrees+i sin 135 degrees)]^4#?
