To do so, we use important results as the periodicity theorem Carton / Bott. The, we study their representations, emphasizing the Twisted Adjoint Representataion, Spin Representation and the Spin-Half Representation moreover using the number of Radon-Hurwitz we study representations of the algebras Cl0,k. / Neste trabalho, estudamos as ´algebras de Clifford Cl(V, ) associadas aos espa¸cos quadr´aticos (V, ), de maneira universal, construtiva e como quantiza¸c˜ao da ´algebra exterior. Classificamos todas as ´algebras de Clifford associadas as espa¸cos quadr´aticos de Minkowski (Rp+q, p,q), onde p,q(u) = u21 + ... + u2 p − (u2 p+1 + ... + u2 p+q), u = (u1, ..., up+q) ∈ Rp+q, as quais denotamos por Clp,q, bem como suas complexifica¸c˜oes. Para tanto, usaremos resultados importantes como o teorema da periodicidade de Carton/Bott. Al´em disso, estudamos as suas representa¸c˜oes, destacando a Representa¸c˜ao Adjunta Torcida, as Representa ¸c˜oes Spin e Semi-Spin e por meio do n´umero de Radon-Hurwitz estudamos as representa¸c˜oes das ´algebras Cl0,k.
