The outermost shell in an atom is also known as the valence shell. When an atom is able to donate or obtain electrons to obtain a noble gas electron configuration, it is said to be stable. Generally, metals are electron donors and non metals are electron acceptors.

An atom in which the outermost level is more than half tends to form is which ions?

An atom in which the outermost energy level is more than half full tends to fill its outermost energy level by adding one or more needed electrons. Such an atom forms a negative ion.


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.


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 of a neutral atom of magnesium are in its outermost energy level?

A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.


Which electrons in a magnesium atom are most likely to be lost?

The outermost electrons, found in the highest energy level, are the most likely to be lost in a magnesium atom. Magnesium has 2 electrons in its outermost energy level, so it tends to lose these electrons to achieve a stable electron configuration.


What is the outermost energy level of an atom is considered full if the level contains?

Outermost energy level is full if there are 8 electrons in the valence shell.


What kind of a tomb tends to lose one electron?

An atom with single electron in its outermost shell


A helium he atom has 2 electrons that are both in the outermost energy level how many more electrons does the atom need to fill its outermost energy level?

It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.


What does atoms have to do to fill the outermost energy level?

they need to either gain or lose electrons to create an octet. It depends on the atom. an octet is when an atom has a full outermost energy level


What is the name of the electrons in the outermost level of an atom called?

The electrons in the outermost level are known as the valence electrons.
