Since 2 electrons fills it's outer shell it is considered an inert gas.
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
Helium is placed at the top of the group-18 in periodic table. Its valence shell contains 2 electrons. It is inert in nature like other elements of group-18.
Helium and hydrogen and group 3 to 12 got 2 valence electron
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
As helium is located in group 18, it has no valence electrons.
Helium has 2 valence electrons. Group 2 elements (alkaline earth metals) also have 2 valence electrons.
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
Helium has the fewest valence electrons, with only 2 valence electrons.
Noble gases contain the least number of valence electrons, with a full outer shell of eight electrons (except for helium, which has two valence electrons).
Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.
To determine the number of valence electrons in an atom, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in group 1 have 1 valence electron, while elements in group 18 have 8 valence electrons (except for helium, which has 2).
To determine the number of valence electrons in an element, look at its group number on the periodic table (group 1-18). The group number represents the number of valence electrons the element has. For example, elements in group 1 have 1 valence electron, while elements in group 18 have 8 valence electrons (except for helium, which has 2).
Helium is placed at the top of the group-18 in periodic table. Its valence shell contains 2 electrons. It is inert in nature like other elements of group-18.
Helium and hydrogen and group 3 to 12 got 2 valence electron
Elements in the same group or column of the periodic table tend to possess the same number of valence electrons. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron, while elements in Group 18 (like helium, neon, argon) have 8 valence electrons except for helium, which has 2.
