What is the molecule responsible for chemical reactions?

The cell itself is responsible for chemical reactions. Chemical reactions are the basis of life, and all parts of the cell work together to make them happen. Specifically the enzyme and mitochondria are often cited as being responsible. The enzymes are proteins that create a binding surface for the chemical reaction and speed the process. The mitochondria act as a digestive system and energizer for the cell.


How many electrons are in the highest occupied energy level atom barium?

2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons


What are electrons that exist in an atoms highest occupied energy level known as?

Those are known as valance electrons, because they determine the kind of chemical reactions that the atom will undergo.


How electrons in an atoms organize?

Electrons occupied certain discrete energy levels around the nucleus.


Where do the electrons in a covalent bond come from?

The electrons in a covalent bond come from the outer energy levels of the atoms involved. Each atom contributes one or more electrons to be shared between them. This sharing creates a stable electron configuration for both atoms.


How many electrons are in the highest occupied energy level of oxygen?

Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.


Which electrons in an atom have the highest energy level?

Electrons in the outermost energy level (valence electrons) have the highest energy level. These electrons are involved in the atom's chemical reactions and bonding with other atoms.


The highest occupied energy level of an atom?

Well, honey, the highest occupied energy level of an atom is called the valence shell. It's where all the action happens, with those sassy electrons strutting their stuff. Just remember, the higher the energy level, the further those electrons are from the nucleus. Keep on shining bright like a diamond, just like those valence electrons!


What is the element in the fourth period whose atoms have the same number of electrons in their highest energy levels that tins atoms do?

bromine, i think


What is an atom's group?

An atom's "group" is its column position in the Periodic Table of the Elements. Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level.


At what stage of reaction do atoms have the highest energy?

Atoms have the highest energy at the transition state of a reaction, also known as the activated complex. This is when the reactants have absorbed enough energy to break old bonds and start forming new ones.
