how many electrons are in the outermost shell of hydrogen?

These elements, including hydrogen (H), lithium (Li), and sodium (Na), all have one electron in their outermost shells. That means that they can achieve a stable configuration and a filled outer shell by donating or sharing one electron with another atom or a molecule such as water.

Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.

Similarly, neon has a complete outer 2n shell containing eight electrons. These electron configurations make helium and neon very stable.

Fluorine (F) and chlorine (Cl), as group 17 elements, have seven electrons in their outermost shells. They tend to achieve a stable octet by taking an electron from other atoms, becoming negatively charged ions: F− and Cl−. Carbon (C), as a group 14 element, has four electrons in its outer shell.

Hydrogen ( Hstart text, H, end text), lithium ( Listart text, L, i, end text), and sodium ( Nastart text, N, a, end text), as group 1 elements, have just one electron in their outermost shells. They are unstable as single atoms, but can become stable by losing or sharing their one valence electron.

A total of 8 electrons can be placed in the outermost shell of an atom. This rule is known as the Octet rule.

The outermost orbitals, 3s2 3p3 , contains 5 electrons. Thus, valence electrons for P is 5.
652304
The other inert gases including argon and xenon also have full outer shells with eight electrons. The inert gases have a valence number of 0.
472205
The innermost shell has a maximum of two electrons but the next two electron shells can each have a maximum of eight electrons.

Physical properties Whereas all other group 8 elements have two electrons in the outermost shell, in ruthenium, the outermost shell has only one electron (the final electron is in a lower shell). This anomaly is observed in the neighboring metals niobium (41), molybdenum (42), and rhodium (45).

The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.

In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element.

Valence electron is the number of electrons present in the outermost orbit of an element . Oxygen has the atomic number 8. As the electronic configuration of oxygen 1s2 , 2s2, 2p4, it has 6 electrons in outermost orbit ( which is 2nd orbit) and no of electrons in this orbit is 6 ( 2+4).

Since krypton is in the far right row of the periodic table, its outermost shell is full with eight electrons. This is one of the happy elements and has an electron configuration of 2-8-18-8. The other inert gases including argon and xenon also have full outer shells with eight electrons.
