How many electrons do hydrogen and helium need to fill their outermost energy level?
Helium already has a full valence shell. Because the first orbital holds two, and the second orbital holds eight...Helium is already filling the first shell with its two electrons, and it has no more electrons to spill into the second orbital, therefore it's one and only shell is full. Hydrogen tends to gain one electron in order to fill its outermost energy level. Hydrogen only has one, but it needs two to fill it's valence shell, so it will gain one. Long story short, helium is already full (that's why it's in the noble gas group) and hydrogen tends to gain one electron, and form a negative ion. No honey it has a number and that is 2 duh!!
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
How many electrons does neutral selenium atom need to fill outermost shell?
Selenium needs two more electrons.
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 electrons in hydrogen valence shell will give it a noble gas configuration?
Two electrons will fill a hydrogen's outer, or valence, shell.
How man electrons would you need to fill the outermost ring of hydrogen?
1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these electrons.
Chlorine is more likely to try an empty its outermost orbital by losing electrons or fill its outermost orbital by gaining electrons?
Chlorine is MUCH more likely to fill its outermost orbital by gaining electrons.
How would an atom of oxygen fill its outermost energy level?
It would gain 2 electrons.
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.

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

When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
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.
What type of bond shares electrons to fill the outermost energy level?
The sharing of electrons occurs in covalent bonding.
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.
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 many electron would fill the outer layer of hydrogen?
Electrons only fill the first layer of hydrogen, giving it only two. The rest of the layers are all 8.
