What chemical characteristics do elements in a group share?
Elements of the same group generally share the same number of valence electrons, which are the electrons in the outer energy level only. These are the electrons that participate in a chemical reaction, so elements in the same group behave similarly in chemical reactions, which makes predictions and generalizations possible.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
What kind of chemical bond is formed when atoms share electrons?
When atoms share electrons, they form a chemical bond, or covalent bond.
Which pair of molecules share the same chemical composition but differ in molecular structure?
Lactose and sucrose share the same chemical composition but differ in molecular structure. Such molecules are called isomers.
When two or more atoms bond together and share electrons they form what?
Two or more atoms that get together and share electrons form a chemical bond.
What chemical properties share the same with beryllium?
Magnesium has some similarities with beryllium.
What is a chemical chain reactionA chemical reaction that causes the next one.(for geoscience Nuclear fission and fusion)?
Share A chemical reaction that causes the next one
What are the similarities of potassium and francium?
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
What causes a chemical bond to?
Bonding occurs when atoms gain,lose,or share electrons in their outer energy level.
What drugs are classified as pregnancy category x by the fda what similarities do some of there drugs share?
What similarities do some of these drugs share in Pregnancy category X
How do organisms share energy that they obtain from the sun?
Organisms share energy from the sun in the food web. A plant converts the energy from the sun into chemical energy, then an animal eats the plant. Sun->Plant Plant->Rabbit Rabbit-> Snake Snake->Eagle Then the foodchain may stop with the Eagle

What similarities did native Americans groups share?
they had a hard life
What similarities do candy and his dog share?
They both are old and worthless.
Which elements tend to share electrons in chemical bonds?
Nonmetals typically share electrons in chemical bonds in order to achieve a stable octet configuration in their outermost energy level. This sharing of electrons allows both atoms involved in the bond to reach a more stable, lower energy state. Examples of elements that commonly share electrons in bonds include oxygen, nitrogen, and carbon.
