Electrons in the outer shell, also known as valance electrons, determine how an atom will react. To be more precise I should add that there are transition state elements whose reactivity is also influenced by some of the inner electrons as well.

What determines how an atom reacts?

The factor in determining how an atom reacts is the valence electrons, ie how many and in what energy level.


Which features of an atom determines how it reacts with other atoms?

The number of protons and electrons in an atom determine its chemical properties. Specifically, the number of electrons in the outermost energy level (valence electrons) dictates how likely the atom is to react with other atoms to achieve a stable electron configuration.


What is the number of electrons in outer shell called?

The number of electrons in the outermost shell is called the valence electrons. These electrons determine the chemical properties of an element and how it interacts with other elements.


What determines whether or not an atom reacts with other atoms is it the electrons on the first shell or the second?

It is predominantly the electrons on the outermost shell (valence electrons) of an atom that determine its reactivity with other atoms. These valence electrons are involved in forming chemical bonds with other atoms.


Which electrons interact to form chemical bonds?

Valence electrons interact to form chemical bonds. These are the electrons in the outermost energy level of an atom, and they are involved in bonding with other atoms to achieve a stable electron configuration.


What happens when sulfur reacts with potassium?

When sulfur reacts with potassium, they form potassium sulfide. This reaction involves the transfer of electrons from potassium to sulfur, resulting in the formation of ionic bonds. The reaction is exothermic, meaning it releases energy in the form of heat.


How does Be obey te octet rule when forming compounds?

Beryllium (Be) is an element in group 2 of the periodic table. It has 2 energy levels and 2 valence electrons in the outermost energy level. It reacts by losing 2 electrons to attain a noble gas structure.


When NAD plus reacts with hydrogen and gains two electrons?

Electrons. ( plus that proton )


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.


Does chlorine react by losing electrons?

Nope, Chlorine reacts if it gains electrons. Not Lose. Apex


How does the elements reacts to each other?

An element reacts with another element by sharing electrons. The elements keep sharing electrons until both elements have a full outer shell.


Why do varied compounds have different colors in their visible emission?

All kinds of waves, including light, have different possible wavelengths and frequencies. What particular wavelength a light wave might have depends on how it was made. Now if two light rays with different wavelengths enter your eye can you tell there were two different wavelengths? The answer is yes, and the way you tell is that your brain reacts differently to the two waves. The way it reacts differently is by giving the two waves "color". So its not really the waves that have different colors its the way your brain interprets the different wavelengths.
