Helium, it is the most inert gas (element ) of all.
Helium has the fewest valence electrons, with only 2 valence electrons.
it has 15 valence electrons (P2) -original answermy answer- That is incorrect An element can only have a Max of 8 valence electrons.Phosphorous has 5 valence ElectronsSource: 10th Grade Chemistry
The valence electrons are involved in forming chemical bonds between atoms. They determine an element's reactivity and ability to combine with other elements to form compounds. In general, only the outermost electrons, known as valence electrons, participate in chemical reactions.

Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.

The element that has a mass number of and two valence electrons is an isotope of calcium.
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.

Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.
valence electrons are the parts of an element that will attach to another element, but only if they reach a certain point. nothing else is a factor. the only other thing added is polarization, which affects how the shape of an atom will come out
In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
