What charge does oxygen have? Assign oxidation numbers for each element in the following compounds. a) H_2CO_3 b) Cr_2O_3 c) Fe_2(MnO_4)_3 d) Ca(ClO)_2 e) Zn(NO_2)_2 What is valency? What is the balanced equation for the oxidation of manganese from solid metal to an ion...
A mass number is a total count of all the protons and neutrons in the nucleus of an atom. Protons are the positively charged particles in the nucleus while the neutrons have a neutral charge. Each particle has a mass count of one. ...
So protons and electrons are a bit like the two different ends of a battery: they have equal and opposite electric charges. Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative ...
Electron Sea Model: The metallic bond, a force that holds together metals, can be explained through the electron sea model, which can also explain the physical properties of the metals. Answer and Explanation:1 In a metal, the atoms are bonded together via the metallic bond, which is differe...

The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Titrations in which completion is monitored by the zeta potential, rather than a titration system indicator are known as zeta-potential titrations. These titrations are used to characterize heterogeneous systems including colloids. One use is determining the point at which a surface charge becomes ze...
... In most cases, the alkaline earth metals are ionized to form a 2+ charge. What is fermium most commonly used for? Since fermium is found only in small quantities and all its isotopes have short half-lives, there is no commercial use for the element. It is, however, used in ...
