What else can I help you with?
Give an example of a covalent compound?
hydrogen molecule (H2) : is single covalent bond where each H atom shares with one electron to complete it's outermost shell (k level) with two electrons and becomes more stable.oxygen molecule (O2) : is a double covalent bond where each (O) atom shares with two electrons to complete its outermost shell (L level) with 8 electrons.nitrogen molecule:is a triple covalent bond where each atom shares with 3 electrons to complete its outermost shell (L level) with 8 electrons and become more stable.
What does each dots in an electron dot diagram represent?
Each dot in an electron dot diagram represents a valence electron, which is an electron in the outermost energy level of an atom. These electrons are involved in chemical bonding and determine the reactivity and characteristics of the atom.
Is there a relationship between the group number of each element and the number of electrons in the outermost energy level?
Yes: group number 1 has 1 valence (outer-shell) electron, group 2 has 2 valence electrons ect, until the noble gases, in group 8, which have 8 valence electrons. This does not include the metals in the middle! H is the first group 1, Be is the first group 2 B is the first group 3, C is the first group 4, N is the first group 5, O is the first group 6, F is the first group 7 and Ne is the first group 8. He is the odd one out: because whilst it is in the eighth group, as it has a full outer shell, it only has two electrons. That is because the first shell only requires two electrons to fill it.
What is the name for an atom that has single electrons in its outermost shell?
Hydrogen, Lithium, Sodium... etc. All of the elements in the first column of the periodic table.
How is the energy level of an elements valence electrons related to its period?
Each period has one more energy level than the last: lets look at group 1 the alkaline metals as an example H - 1 - one energy level Li - 2,1 - two energy levels Na - 2, 8, 1 - three energy levels K - 2, 8, 8, 1 - four energy levels ect
How many electrons would you need to fill the outermost ring of hydrogen?
Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.
What is the number of electrons in the outer energy of H plus?
An atom of Hydrogen (H) has one electron (-1) and one proton (+1), and is uncharged (0). H+ indicates that the Hydrogen atom has lost an election (-1) but still has the proton (+1) and thus has a positive charge (H+). Because it only had one electron to begin with, when H becomes H+ it does not have any electrons left. Therefore, H+ does not have any electrons.

Why would a hydrogen attach to chlorine?
Hydrogen has one valence electron. To form a compound, it must follow the octet rule, which states that the total outermost orbital (valence) contains eight electrons. The Chlorine atom contains seven valence electrons. H(1) + Cl(7) = 8 (follows the octet rule)

How many valence electrons are in a hydrogen ion?
It depends on what kind of ion:If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).
How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
What is the name for an atom that has single electrons in its outermost shell?
Hydrogen, Lithium, Sodium... etc. All of the elements in the first column of the periodic table.
In what ways are the electron configurations of H Li Na K Rb and Cs similar?
The electron configurations of H, Li, Na, K, Rb, and Cs are similar in that they all have one valence electron in their outermost energy level. These elements belong to the alkali metal group in the periodic table and tend to exhibit similar chemical properties due to their outermost electron configuration.
How is the energy level of an elements valence electrons related to its period?
Each period has one more energy level than the last: lets look at group 1 the alkaline metals as an example H - 1 - one energy level Li - 2,1 - two energy levels Na - 2, 8, 1 - three energy levels K - 2, 8, 8, 1 - four energy levels ect
What is the Lewis dot structure for Cl?
Chlorine, like all halogens, has seven dots in its Lewis dot diagram.To figure out the Lewis dot structure, look at the valence electrons. These are electrons in the outermost shell.1. Figure out the group it is in at the periodic table or figure out its configuration electron.. *v=valence electronsAlkali Metals: 1v*Alkaline Earth Metals: 2vGroups 3-5, 7-10, 12: 2vGroups 6 and 11: 1vGroup 13: 3vGroup 14: 4vGroup 15: 5vGroup 16: 6vGroup 17: 7vGroup 18: 8vChlorine: Group 17, Halogens: 7 valence electronsElectron Configuration: 1s2 2s2 2p6 3s2 3p5Shell Electrons: 2, 8, 22. The valence electrons are the number of dots you draw around the chemical symbol, in this case, chlorine, or Cl.So, the symbol is 7 dots around Cl.Eight electrons surrounding all sides:: -[:Cl:]:except the top and bottom are horizontal.
