What is the relationship between electronegativity and reactivity of metals?

Explanation: metals are less electronegative that is more electro positive . they have more tendency to donate electrons to elements having more electro-negativity . so more the electro-positive the metal more the tendency to react .

What happens in the reactivity trend of the elements?

Chemical reactivity of the elements Period – reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. Group – reactivity decreases as you go down the group.

How do you know if an element is more reactive than another?

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

What happens to the electronegativity as the atomic radius increases?

From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.

Are elements more reactive down a group?

The reactivity of Group 1 elements increases as you go down the group because: the atoms get larger as you go down the group. the attraction between the nucleus and outer electron gets weaker as you go down the group – so the electron is more easily lost.

What is the electronegativity trend?

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

What is the electronegativity of an atom?

Electronegativity is a chemical property which describes how well an atom can attract an electron to itself. Values for electronegativity run from 0 to 4. Electronegativity is used to predict whether a bond between atoms will be ionic or covalent. It can also be used to predict if the resulting molecule will be polar or nonpolar.

How does electronegativity change as you go down the group?

Reactivity decreases as you go down the group. ** The farther right and up you go on the periodic table, the higher the electronegativity, = harder exchange of electron. Metals: Reactivity decreases as you go from left to right across a period.

Which non-metals have the highest reactivity?

Extremes in Electronegativity causes increased reactivity. Florine with an electronegativity of 4.0 is the most reactive of all non metals. It is also the element with the greatest electronegativity. The I A Alkaline elements are the most active metals.

What is the relationship between electronegativity and electrical conductivity?

Elements with a high electronegativity are generally nonmetals and electrical insulators and tend to behave as oxidants in chemical reactions. Conversely, elements with a low electronegativity are generally metals and good electrical conductors and tend to behave as reductants in chemical reactions.
