This is called a trivalent metal ion. Examples: Al3+, Fe3+, etc.
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
When the element bonds with another element it accepts electrons (it does not give them away) and becomes negatively charged.
Metals, particularly the alkali metals- lithium, sodium, potassium, etc
Lewis dot structures are used to represent the covalent electrons of an element. It can be used to show the sharing of covalent electrons in a covalent bond or just to show the covalent bonds in general.
The most electronegative element is fluoride. The most electropositive element would be Francium however there has never been enough of it collected to perform the measurement on.
As an element of Alkali metals family, It will give away its electrons very easily to produce monovalent Fr+ ion
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
That depends on the reaction, and the gain of electrons is refereed to as reduction.
Two electrons in the outer shell of radium.
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
The smallest particle that has characteristics of that element is the atom. The atom is made up of a certain amount of protons, electrons and (neutrons) and those are what give the characteristics of that element to that atom.
