Which atom does not need 8 electrons in it outer energy level to be stable?
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
Explain how valence electrons in an atom are used to form a full outermost energy level?
Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
What do atoms want to have for their outer energy level?
Atoms want to have a full outer energy level of electrons, typically either 2 or 8 electrons, to become stable. This is known as the octet rule, in which atoms tend to gain, lose, or share electrons to achieve a stable electron configuration like the noble gases.
Argon is a stable gas with a very high ionization energy Which statement explains why?
Argon is a stable gas with a high ionization energy because it has a full outer electron shell, making it energetically unfavorable to lose or gain electrons. This stable configuration results in a high ionization energy, as a significant amount of energy is required to remove an electron from an atom of argon.
How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
What is it called when an atom has an outer energy level is filled with electrons?
it is called complete or completely stable
What are the electrons in the outer most energy level of an atom called?
The electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration.
How many many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?
Generally speaking, it would be 8 electrons, but there are many exceptions.
What is the most stable state of an atom called?
The most stable state of an atom is called the ground state. This is when the electrons occupy the lowest energy levels available to them.
How many electrons are need in the outer energy levels of most atoms for the atom to be chemically stable?
8 are traditionally needed in the valence shell.
How many additional electrons are required to give nitrogen the required number of electrons in its outermost energy level?
Nitrogen has five electrons in its outermost energy level (the second shell), which can hold a maximum of eight electrons. To achieve a stable octet configuration, nitrogen requires three additional electrons. Thus, three additional electrons are needed to fill its outermost energy level.
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
Which atom does not need 8 electrons in it outer energy level to be stable?
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
How many electrons are needed to be gained or lost in aluminium to achieve stable electron configuration?
Only three electrons.
When is an element usually reactive?
Elements are usually reactive when they have fewer electrons in their outermost energy level than is needed to achieve a stable configuration. This leads to them readily gaining, losing, or sharing electrons in order to attain a full outer shell and become more stable.
What makes the electrons more stable?
Electrons are more stable when they are in lower energy levels, closer to the nucleus of an atom. They are also more stable when they are paired with another electron in the same orbital, following the Pauli exclusion principle. Additionally, atoms are more stable when their outermost energy levels are filled with electrons, resulting in a full valence shell.
