Explain the role of an element's electrons in determining its chemical reactivity?

Electrons differ in the amount of energy they have and how tightly they are held by the protons in the nucleus. Based on these properties, chemists describe an atom's electrons as belonging to certain energy levels. Usually it is the electrons in the highest energy level of an atom that determine how that atom reacts.

∙ 13y agoI believe that if the element has a low amount of valence electrons they are more reactive. For example, Lithium, sodium, potassium etc. are very reactive. But the noble gases aren't as reactive because they have more electrons. It depends on how "grabby" they are for electrons..

What is electronegravity?
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
Why do elements in the same group or column of the periodic table have similar properties?
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
Does the amount of protons an element has affect chemical bonding?
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
How easily an element reacts with other elements is a measure of its what?
Measure of its chemical reactivity.
What information is used to predict chemical reactivity?
The electronegativity of the elements help this prediction.
Elements that are in the same have same number of electrons in the outer these outer electrons are so important in determining the chemical of an element that a special way to represent them has been?
- Electrons in the outer shell are important for the chemical reactivity of elements.- You think probable to a Lewis diagram.
What is electronegravity?
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
What do the elements in oxygen family have in common?
All elements have same number of valence electrons (two) and hence they have similar reactivity and chemical properties.
Why do elements in the family have similar properties?
Because they have the same number of valence electrons, which are the primary determinants of chemical reactivity.
What is true about elements in each groups?
They have the same number of valence electrons and so have similar reactivity and similar properties.
Why do elements in the same group or column of the periodic table have similar properties?
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
What do elements within a group have a similar number of?
Chemical elements that are in the same group within the periodic table have the same numbers of electrons in the outermost shell. This gives them similar reactivity.
Reactivity of actinides?
The reactivity of actinides varies among the elements because the number of Valence Electrons in actinides have 3-6 valence electrons therefore the reactivity varies as well. -JB
What do the families in the periodic table have in common?
Families in the Periodic Table of Elements have the same amount of valence electrons.
What is the chemical behavior of an atom is determined by?
By using the activity series (sometimes called reactivity series) which orders metals by their reactivity with other metals, one can determine the reactivity of a metal
What info is used to predict chemical reactivity?
For chemical elements the most important factor is the electronegativity.
What is the significance of noble gases?
Because they have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity but now they are not considered as inert elements.
