This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
What else can I help you with?
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The symbol for an element that does not need eight electrons to have a full set of valence electrons is typically found in Group 1 or Group 2 of the periodic table. Examples include lithium (Li) from Group 1 and beryllium (Be) from Group 2. These elements follow the duet rule or satisfy the octet rule in a different way.
If the atomic mass of lithium is 6.941 and it exists as lithium-6 and lithium-7 what percent of the isotope is lithium-7?
To determine the percentage of lithium-7, we need to calculate the relative abundance of each isotope considering their atomic masses. Given that the atomic mass of lithium-6 is 6.015 and that of lithium-7 is 7.016, the percentage of lithium-7 is approximately 92.5% based on natural abundance.
How many electrons does neutral selenium atom need to fill outermost shell?
Selenium needs two more electrons.
How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
Can the element sulfur combine with the element lithium?
Sulfur can form compounds with lithium, such as lithium sulfide (Li2S) or lithium polysulfides. These compounds are typically formed through chemical reactions where lithium donates its electrons to sulfur to create stable compounds.
How many electrons does an atom of lithium need to lose to form an ion with a plus 1 charge?
ONE electron Lithium is a Group (I) metallic elementy like sodium, potassium etc., It has one electron in its outer most energy shell , which it readily ionises (loses). Li(g) = Li^(+) + e^(-)
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.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
Why does a lithium atom develop a positive charge?
Lithium only needs to lose one electron (and thus become positive) to achieve the same electron configuration as Helium which is extremely stable. The other option would be to gain 7 electrons to become like Neon which would be very energetically unfavorable.
How many valence electrons need to be accommodated in the Lewis structure for LiCl?
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
What atom has 3 protons 4 neutrons and 3 electrons?
I've edited the question so it makes any sort of sense. The answer would be 4 electrons. You need an equal number of electrons and protons to be neutral. Neutral just means neither positive or negative. Electrons are -1 and protons are +1. The only way to not be particularly one or the other is to have them both in equal amounts.
How many electrons N2 need to share to be stable?
Three pairs of electrons.
How many electrons does it need to have in the outermost energy level filled?
8 electrons
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The symbol for an element that does not need eight electrons to have a full set of valence electrons is typically found in Group 1 or Group 2 of the periodic table.
