There are two types of chemical bonds, ionic and covalent. Ionic bonds involve the complete transfer of electrons from one atom to another. Covalent bonds involve the sharing of electrons between the two atoms.
Covalent Bond
covalent
The ion given is formed when the neutral arsenic atom gains three electrons.
current
its radius increases due to repulsion of same charges...
Electricity is the name given to the flow of electrons. Conventionally, the electrons flow from the negative terminal to the positive. An individual electron does not make the whole trip instantaneously - an electron moves on to an atom, which then has an excess of charge, and the spare electron is passed on to the next atom, and so on.electrons are charged particles and the flow of these electrons constitute electricity.
No.In a given circuit, looked at from a particular direction, this may be true. But it's certainly not true in general.
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.
As you can see from the periodic table, mostly, metallic atoms lose electrons such as Sodium, Magnesium, Iron, Calcium etc. These are all atoms that have four or less electrons in their last/outer shellHowever, this is only in an ionic bond where electrons are taken or given but not in covalent bonds. Covalent bonds involve the sharing of electrons rather than giving/taking
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.

In co-ordinate bonds, both electrons of the bond pair is given by the same atom.
Given that electrons repell other electrons while attracting protons in atomic nucleii, electrons interact in covalent bonds by finding an arrangement which brings them as close as possible to as many protons as possible while remaining as far as possible from other electrons. The particular feature of a covalent bond which differentiates it from other types of bonds is that a given electron does not limit itself to a single atomic nucleus, but orbits multiple nuclei.
Covalent bonds are bonds in which the valence electrons are shared, note the "co", meaning shared or together, in covalent, valent meaning electrons. Ionic bonds occur when the electronegativity difference between two given elements is greater than 2.7, resulting in an electron being removed entirely from the element with a lower electronegativity. The resulting increase in charge for the less electronegative element and decreased charge for the more electronegative element causes the two elements to be so strongly attracted to each other that is is rather difficult to separate the two.
How many bonds can atom form? not have ok so its answer is atoms are polygomus..they can make as many bonds as they desire . By its valence number. Remember the octet rule, atoms form bonds in order to have eight electrons in their outer shell (with the exception of hydrogen and helium.) Atoms can form multiple covalent bonds if they need more than one electron to complete their valence shells. Oxygen, for example, bonds with itself to form 2 bonds between the atoms (since each atom needs to share 2 electrons). i have given three answers so ithink you can now better understand
