You can devise your own way of memorizingthe first 20 elements. It may help to associate each element with a name or a word that makes sense to you. Here are the names and symbols of the first elements. The numbers aretheir atomic numbers, which is how manyprotonsare in an atom of t...
After a nice hot dip in the potassium bath, the aluminosilicate emerges compressed by potassium ions. The compression creates a protective layer on the glass and gives it strength that normal glass doesn't have. And the environmentally conscious can rest easy -- Gorilla Glass is recyclable. ...
intricate data from the oxygen experiments. Stephan Irle helped interpret the model data, which revealed in high resolution the atomic structure of the solution—that is, how many water molecules surround each oxygen on a nitrate and how many potassium ions also...

A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total betwe...
How many protons does argon have? What is the molar mass of argon? How many neutrons are in argon? What is potassium-argon dating used for? What state of matter is argon? What is the electronegativity of argon? What is tellurium used for?
All elements are arranged in the periodic table by their atomic number -- the number of protons in their nucleus. Aluminum's lucky number is 13, so an aluminum atom has 13 protons. It also has 13 electrons. The elements located above and below aluminum on the periodic table form a ...
The alcohol reacts with potassium dichromate to produce: chromium sulfate potassium sulfate acetic acid water The silver nitrate is a catalyst, a substance that makes a reaction go faster without participating in it. The sulfuric acid, in addition to removing the alcohol from the air, also might...
How many electrons are present in the 2nd energy level of potassium? What is affect of d-subshell in atoms lacking it? Balance the equation: CN^- + MnO4^- = CNO^- + MnO_2 , using half-reactions. In a Hydroxide ion, where does it get the 9th and...
