number of electrons

Equivalent mass is equal to the molecular or atomic mass divided by the number of electrons involved in the reaction per molecule, atom or ion. For example in the reaction, two electrons are needed to produce one molecule of hydrogen gas. So, 2 Farada..

A local electronic goods store maintained a record of the number of items sold in a month. How many refrigerators were sold in the month? => 40 or 30 or 20 or 10..

Electronic Configuration - The distribution of electrons in different orbitals is known as its electronic configuration. This characterizes each electron in an atom. The electronic configuration is expressed by indicating the principal quantum ..

The last electron enters into 5f-orbital in these elements. The electronic configuration of actinides is given below. The general electronic configuration of these elements is 5f 1 - 1 4 6d 0 - 1 7s 2 . Element Symbol Atomic number Ele..

Valence electrons of an atom are responsible for chemical reactions as they take part in them. Elements having same number of valence electrons in their atoms possess similar chemical properties. All alkali metals have one valence electron in their atom. T..

Metals are the elements which form positive ions by losing electrons, while non-metals always gain electrons. All metals (except hydrogen) form positive ions by loosing electrons. Metals have 1 to 3 electrons in the outermost shell of their atom and non..

The distribution of electrons in different orbitals is known as electronic configuration of the atom. The orbitals are indicated by a box (square or circular) and electrons are indicated by arrows. An empty square will mean an empty orbital, while a single electro..
