Which element has four valence electrons.

Valence Electrons. The electrons in the outermost shell are the valence electrons the electrons on an atom that can be gained or lost in a chemical reaction. Since filled d or f subshells are seldom disturbed in a chemical reaction, we can define valence electrons as follows: The electrons on an atom that are not present in the previous rare gas, ignoring filled d or f subshells. The valence electrons for main group elements are those with the highest n level. For example, gallium (Ga, atomic number 31) has the electron configuration [Ar]4s 2 3d 10 4p 1, which contains three valence electrons (underlined). The completely filled d orbitals count as core, not valence, electrons. Transition elements or transition metals.Its valence electron shell is 2s 2 2p 1, so it has three valence electrons. The third electron will go on another side of the symbol: \[\mathbf{\dot{Be}}\mathbf{:}\] Again, it does not matter on which sides of the symbol the electron dots are positioned. For carbon, there are four valence electrons, two in the 2s subshell and two in the 2p subshell Valence electrons for representative elements. Lithium has a single electron in the second principal energy level, and so we say that lithium has one valence electron. Li: 1s 2 2s 1 (the electron in the 2s energy level is the valence electron) Beryllium has two valence electrons: Be: 1s 2 2s 2 (the two electrons in the 2s energy level are the ... While most atoms obey the duet and octet rules, there are some exceptions. For example, elements such as boron or beryllium often form compounds in which the central atom is surrounded by fewer than eight electrons (e.g., BF₃ or BeH₂). In contrast, many elements in the third-row and beyond have been observed to exceed the octet rule ...

The presence of valence electrons can determine the element's chemical properties and whether it may bond with other elements: For a main group element, a valence electron can only be in the outermost electron shell. An atom with a closed shell of valence electrons tends to be chemically inert. An atom with one or two valence electrons more ...For instance, let us look at aluminum. Aluminum is the first element of its period with electrons in the 3p shell. This makes the first ionization energy comparably low to the other elements in the same period, because it only has to get rid of one electron to make a stable 3s shell, the new valence electron shell.The electron configuration shows the distribution of electrons into subshells.
