Elements from which group undergo the fewest chemical reaction?
chemistry
Why phenol undergoes electrophillic substitution reactions?
because, phenol it self neucleophilic group.
Why are elements in the same group undergo the same kinds of reactions?
Elements in the same group have similar chemical properties because they have the same number of valence electrons that are used in chemical reactions.
What group of biological molecules can speed up chemical reactions by lowering a reactions activation energy?
Biological catalysts are called 'enzymes'.
Which term is defined as all chemical reactions that are required to sustain life?
METABOLISM. Metabolism is the sum of the group of reactions to obtain energy
What is substitute reaction?
A substitution reaction is when a functional group in a particular chemical compound that is replaced by another group. Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. A chemical compound is a pure chemical substance consisting of two or more different chemical elements, which can be separated into simpler substances by chemical reactions.
What is the most reactive group of nonmetals whose atomsgain one electron in chemical reactions called?
The halogens, group 17
What is in a molecule influences the way that molecule reacts?
Functional groups are responsible for chemical reactions of molecules.
Which chemical family has atoms with the fewest number of electrons?
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
Which group of biological molecules can speed up chemical reactions by lowering a reaction's activation energy?
Enzymes
Which group has the fewest representatives in congress?
Hispanics
Why is group VIIIA called noble or inert gases?
According to the classical shell model for electrons, the group 18 elements have a fully filled outer shell, rendering them inert to most chemical reactions (little tendency to participate in chemical reactions ) they are called noble or inert gases
