What seems to be the relationship between atomic radius and the reactivity of the elements in group 1 and 2?

Radius and Reactivity As atomic number increases, so does an atom’s radius. The outermost electron is held less tightly and escapes more readily. Therefore, the alkali metal with the higher number is more chemically reactive. This makes francium the most reactive of the alkali metals.

What is the relationship between atomic structure and reactivity?

The location of electrons in an atom can be described as concentric shells around the nucleus of the atom. 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.

Why is the larger atom more reactive?

The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity.

What is the relation between atomic size and reactivity of elements in group of metals?

Metals with a big atomic size and non- metals with a small atomic size are more active than others. In a group, the reactivity of metals increases from top to bottom and that of non- metals decreases from top to bottom. The atom having two electrons in its valence shell is known as duplet.

What is the relationship between the atomic number and the atomic radius?

Going from left to right across a period (horizontal row) of the periodic table the atomic radius or size decreases as the atomic number increases. However, moving from top to bottom within a group (vertical column) the atomic radius increases as the atomic number increases.

What is the connection between atomic radius ionization energy with the reactivity of elements?

Therefore the closer the electron to the nuclear the higher the attraction force, and thus the higher the energy required to overcome this attraction and remove the electron. Therefore the smaller the radius the higher the ionization energy, and the bigger the radius the lower the energy need.

What is atomic reactivity?

Reactivity is a measure of how easily an element will combine with other elements to form compounds. Some elements are unreactive and need energy putting in others will react spontaneously and easily. Reactivity is a measure of how easily an element will combine with other elements to form compounds.

What is reactivity of an atom?

Reactivity is a measure of how easily an element will combine with other elements to form compounds. Reactivity is a measure of how easily an element will combine with other elements to form compounds. Some elements are unreactive and need energy putting in others will react spontaneously and easily.

How does atomic radius affect an atom?

Atomic radius is the distance from the atom’s nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This results in a larger atomic radius.

How do the atomic radius and reactivity compare among the halogens?

The reactivities of the halogens decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size with an increase of electronic energy levels. This lessens the attraction for valence electrons of other atoms, decreasing reactivity.

What’s the difference between atomic size and atomic number?

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element’s nucleus. It is the average weight of an element.
