Elements in Group I have 1 outermost electron, elements in Group II have 2 outermost electrons, and so on. The outer (valence) electrons take part in chemical reactions, and are therefore responsible for ...
WebThe following chapter will explore periodic properties that will be explained by quantum mechanics, as covered in Chapter 3. Figure 1: A neuron with its dendrites and long axon. Signals in the form of electric currents reach the cell body through dendrites and across synapses, stimulating the neuron to generate its own signal sent down the axon. WebThe elements can be classified as metals, nonmetals, or metalloids. The elements within the same group of the periodic table tend to exhibit similar physical and chemical properties. Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons).
