When two atoms with different electronegativities are bonded together, a bond_ exists. these are displayed with an arrow originating at the atom with the_ electronegativity and pointing toward the atom with the_ electronegativity. partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. since the atom with a higher electronegativity will have a stronger ability to attract electrons, it will have a partial_ charge. the atom with a lower electronegativity will have an equal and opposite_ charge. as the difference in electronegativity increases, the resulting magnitudes of the partial charges will_. bond character is used to describe the severity of the electronegativity differences between the two atoms involved in a bond. bonds that have character correspond to a larger difference in electronegativities, and bond character corresponds to a smaller difference. for example, increasing the electronegativity of atom "a" in the phet simulation and decreasing the electronegativity of atom "b" will result in a bond that is_ ionic in character.

Polarity,less,more,negative,positive,increase,iso ionic

Explanation:

When two atoms with different electronegativities are bounded together a bond polarity exist.

        These are displayed wth an arrow originating at the atom with less electronegativity and pointing towards the atom with more lectronegativity.

        Since the atom with a higher electronegativity will have stronger ability to attract electron it will have a partial negative charge.The atom with lower electronegativity will have an equal and opposite positive charge.

   As the difference in the electronegativity increases the resulting magnitude of the partial charge will increase.

 For example increasing the electronegativity of atom A in the phet stimulation and decreasing the electronegativity of atom B will result in a bond that iso ionic in character.

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
