Which kind of bond electrons given or taken?
In an ionic bond, electrons are transferred from one atom to another, resulting in one atom gaining electrons (anion) and the other atom losing electrons (cation). In a covalent bond, electrons are shared between atoms, allowing them to complete their valence shells.
Why a substance that oxidised is called a reducing agent and why a substance that is reduced is called an oxidising agent?
It is because when a substance is oxidized, it loses electrons which are taken up by other so that is gets reduced.This is why it is called reducing agent. Similarly, the substance reduced is called oxidizing agent.
Colvalent bonds can best be described as a donating of electrons?
There are two ways to answer this. The first way would be for a person who is not very familiar with chemistry, and the second for someone who is. First description: A covalent bond can be best described as a bond between to atoms which share electrons. This is different from ionic bonds where electrons are taken from one atom and placed onto another. Second description: A covalent bond is an overlap of electron densities of same sign or potentialities (two bonding orbitals as opposed to antibonding) , which can be described by their orbital wavefunctions. I hope one of these answers suits you.
How do you know when a bond is ionic or covalent?
An ionic bond is one in which electrons are gained/lost, ions are formed, and they attract, forming an ionic compound (e.g., HCl, H2SO4,Li2O) A covalent bond is one in which electrons are shared, and depending on the size of the atoms involved, could be polar (H2O) or nonpolar (N2).
How do the number of valence electrons affect how likely a substance is to react with another substance?
The number of valence electrons is the number of electrons in the outer energy ring of an atom. The most electrons the first energy level of any atom can hold is two. The rest is 8. If the outer energy level is full, the atom will be less reactive because it cannot add any more electrons to it's current outermost energy level. If it only needs one or two more electrons to fill it's last energy level or if it only has one or two in it's last energy level, it will be more reactive, because it only needs to gain a few or lose a few to be full.
Is energy given or taken off with electrons?
It is given off
Which kind of bond electrons given or taken?
In an ionic bond, electrons are transferred from one atom to another, resulting in one atom gaining electrons (anion) and the other atom losing electrons (cation). In a covalent bond, electrons are shared between atoms, allowing them to complete their valence shells.
Which electrons are shared in molecules?
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
What information is given in redox half-reactions?
How many electrons are taken up by an oxidant in the 1st halfreaction (oxidant reaction),and how many electrons are given free by a reductant in the 2st halfreaction (reductant reaction)
What happens when an atom loses and electrons?
Well, an atom that loses an electron does not just "lose" it in space, the electron is taken away by another atom or molecule. So the electron sticks to the new molecule and forms an ion with a charge (given that the original atom was a neutral one). When this happens inside the body some really dangerous compounds can be formed, these are called "free radicals"
What is an atom that has given up or taken on electrons?
I believe you mean an ion, which is an atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. atoms that lose electrons are metals that become positively charged cations. atoms that gain electrons are non-metals that become negatively charged anions.
Do you believe a person who has taken merchandise from his company just a few times should be given another chance?
no
What bond results from the sharing of electrons?
When thinking of bonds, always associate "sharing" with covalent (molecular) bonds. Atoms will share electrons in order to become stable, and depending on the element, will share them equally or unequally. "Transfer" refers to ionic bonds, in which electrons are given/taken.
What type of bonds form as the result of electron sharing?
When electrons are shared in two or more different atoms, it is known as the scientific term, Convalent Bonding. When electrons and given and taken in, otherwise known as tranferring electrons from one atom or another, is called Ionic Bonding.
What information is given in redox half-reaction?
How many electrons are taken up by an oxidant in the 1st halfreaction (oxidant reaction),and how many electrons are given free by a reductant in the 2st halfreaction (reductant reaction)
What is the antonym of taken beginning with G?
Antonym: noun: a word that means the opposite of another word.Taken: past participle of takeAntonym of Taken: Given: past participle of give.
Another phrase for granted?
if by granted you mean something that is taken to be true, then maybe consider: "given that___" or "given that ___ it suffices to say ___" "assuming that___" "if___ then___" "supposing that ___"
