Transition Metal Definition: Let us assume that an element has partially filled d-orbitals or it can form a stable cation when it has incompletely filled d-orbitals. Such element is said to be a transition metal. The examples of transition metals are Ni, Cu, and ...
Name the four common halogens and tell the normal phase of each. Which one is the most reactive of all elements? What is an ionic bond? What type of substance form ionic bond? Classify each element as an alkali metal, alkaline earth metal halogen, or noble gas. A) F B) Sr C) K ...
Hobbyist Rock Tumbler: The machine above is a Thumler's Model B rock tumbler. It is one of the better hobbyist grade tumblers, and it tumbles about ten pounds of rock. It has a metal barrel with a rubber liner. Many Model B rock tumblers have been in reliable use for decades. ...

Much of the funding and industrial activity in advanced reactors is centered in the US, where several companies are close to demonstrating their technology. Kairos Power is building reactors cooled by molten salt, specifically a fluorine-containing material called Flibe. The company received a construc...
The most active element of the group is Fluorine! Write the Lewis structure for O2 The composition of a compound contains only C, O, and Hatoms. What type of bond does the compound have? All NON-Metals so bonds must be COVALENT According to the periodic table, which twoelementsin each ...
Add a further proton, another electron, and two more neutrons, and you'll have an atom of the metal lithium (symbol Li). Add one proton, one neutron, and one electron and you get an atom of beryllium (symbol Be).See how it works? In all atoms, the number of protons and the ...

This leaves the metal with a positive charge and the non-metal with a negative charge, so they are positive and negative ions that attract one another. A simple example is sodium fluoride. Sodium has three shells, with one valence electron in the outermost. Fluorine has two shells, with ...
The chemical name is composed of the name of the metal,which is written first,followed by the name of the nonmetal,which has been modified to an identifying stem to which is added the suffix-ide. For example,sodium chloride,NaCl is composed of one atom each of sodium and chlorine.The ...
