they contain electrons, which are negatively charged and revolve at high speed around the nucleus of an atom. the first shell (the one nearest to the nucleus) can hold a maximum of 2 electrons. the second shell can hold a maximun of 8 electrons. If there any remaining electrons they will go on the third shell. the third shell can hold a maximum of 18 electrons. the shells closest to the nucleus (inner shells) must contain their maximum number of electrons before attempting to fill the energy levels to a higher energy.
What else can I help you with?
How many electrons does each hydrogen atom have in its valence shell?
Hydrogen doesn't really have a valence shell. It has one electron only.
What is the name given to the electron shell that contains the most reactive electrons?
The outermost electron shell in an atom is called the valence shell. It contains the most reactive electrons because these electrons are involved in forming chemical bonds with other atoms.
When full the innermost electron shell of an atom contains electrons and the outemost shell contains electrons?
When full, the innermost electron shell of an atom contains 2 electrons, and the outermost shell contains 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full outer shell of 8 electrons.
How many electron shells does the largest atom have?
The largest atom is calcium which has 4 shells.
What is an atom shell?
An atom shell is the outermost region of an atom where its electrons are located. It defines the boundary of an atom and determines its chemical properties, including how it interacts with other atoms in chemical reactions. The number and arrangement of electrons in the atom shell determine an atom's reactivity and stability.
How many electrons does each hydrogen atom have in its valence shell?
Hydrogen doesn't really have a valence shell. It has one electron only.
An atom contains seven electrons in its outermost energy level the atom is what?
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
Each atom is left with a what outer shell?
Electron outer shell tee hee =^-^=
What is the octet electrons?
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
The particles that make up an atom are?
Nucleus, which contains protons and neutrons Energy Shell/Electron Cloud, which contains electrons
What is the name given to the electron shell that contains the most reactive electrons?
The outermost electron shell in an atom is called the valence shell. It contains the most reactive electrons because these electrons are involved in forming chemical bonds with other atoms.
What is the overall of an atom?
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
What is the outer shell of an electron called?
The electron shell is also called the principle energy level in chemistry and atomic physics. The shells starting closest to the nucleus names go from shell 1 or shell K, shell 2 or shell L,shell 3 or shell m, etc. Each shell contains a certain amount of electrons the first shell starts with two and the number increases for each shell.
How many shells in lithium?
The number of electron shells in a normal Lithium atom is 2. It has an electron configuration of 1s22s1
