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 one way atoms fill their outermost energy level?

Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.


An atom with an incompletely filled outermost energy level is likely to be?

An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.


How can atoms with fewer than 8 valence electrons fill their outermost energy level Use either sulfur or magnesium to explain the process?

Atoms with fewer than 8 valence electrons can fill their outermost energy level by forming chemical bonds with other atoms. For example, magnesium can lose 2 electrons to achieve a full outer energy level, becoming a +2 cation. Conversely, sulfur can gain 2 electrons to fill its outer energy level, becoming a -2 anion. Both processes result in stable, filled outer energy levels for the atoms involved.


When atoms share electrons to fill their outermost energy levels they form?

When atoms share electrons to fill their outermost energy levels, they form covalent bonds. In a covalent bond, electrons are shared between atoms to achieve stable electron configurations.


How may electrons fill the outermost energy level of an atom?

8


How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.


Do noble gases have the maximum number of electrons in their outer energy level?

Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.


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.


How might an atom of oxygen fill its outermost energy level?

An oxygen atom can fill its outermost energy level by gaining 2 electrons through bonding with other atoms. This allows it to achieve a full valence shell of 8 electrons, following the octet rule. Alternatively, it can lose 6 electrons to achieve a full valence shell.


How many more elections are needed to fill the outermost energy level?

To determine how many more elections are needed to fill the outermost energy level of an atom, you need to know the number of electrons already present in that level and the maximum capacity of that level. The outermost energy level can hold a maximum of 8 electrons (following the octet rule) for main group elements. Subtract the number of existing electrons from 8 to find out how many more are needed to fill the level. For example, if there are 5 electrons in the outermost level, 3 more are needed to fill it.


How many valence electrons does it take to fill the outermost energy level?

The number of valence electrons needed to fill the outermost energy level varies depending on the atom's position on the periodic table. For most elements, the outermost energy level can hold up to 8 electrons to become stable. However, elements in the first few periods may require fewer electrons to fill their outermost level.


How would an atom of oxygen fill its outermost energy level?

It would gain 2 electrons.
