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?
The dots are the valence electrons in the outermost shell of an element. The number of valence electrons are the group number of the element (H=1, O=6, C=4 etc.)
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.
How does the arrangement of the outer electrons in an atom determine how the atom bonds to others and forms materials?
Atoms react to attain completely filled outermost orbit.they can form ions,lose,gain or share electrons...if it requires less electron sharing then it will form single bond. Eg:H+H->H2 They will share one electrons. Oxygen requires two electrons for complete outer shell so it will share two electrons with other oxygen atom.thus they will have 4electrons in total.
What is the ocxidation state of CI in HCIO2?
HClO2 As a yardstick, always use oxygen at '-2' . There are a number of exceptions, but when learning oxidation states, think!!! Oxygen ; -2. In HClO2 there are two oxygens hence 2 x -2 = -4 for the oxygen component. Hence the 'H' & 'Cl' must sum to '+4' ; for the neutrally charged molecule. So 'H' can only oxidise one electron , then 'H' is '+1' . This leaves '+3' for the chlorine component. So Chlorine is in oxidation state '+3' Oxidation states of atoms in a molecule refer to the number of electrons in the outermost energy shell that are involved in bonding. Since 'H' has only one electron it can only use that one electron to bond hence its oxidation state is '+1'. However, a chlorine atom has seven electrons in its outermost electron shell, three of these electrons are involved in bonding with the oxygen and hydrogen . NB; Chlorine has the ability to Disproportionate, that is both loose and gain electrons. Think water and chlorine forming HCL & HClO. Hope that helps!!!!
How many electrons would you need to fill the outermost ring of hydrogen?
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 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 electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
Why do you think the noble gases do not have electronegativity values?
The noble gases have outer electron shells that are completely full. Therefore, they dodo not form ordinary compounds and a different method has to be used to define their electronegativity.Electronegativity for noble gases have been determined using the Allred-Rochow scales. Their values are :He=5.50, Ne=4.84, Ar=3.20, Kr=2.94, Xe=2.40.The Mulliken-Jaffe scale lists their electronegativities as:He=3.49, Ne=3.98, Ar=3.19, Kr=3.00, Xe=2.73, Rn=2.59 (F=3.91, H=2.25).The Allen electronegativity scale (Spectroscopic electronegativity scale) lists the EN of noble gases asHe=4.16, Ne=4.79, Ar=3.24, Kr=2.97, Xe=2.58 (F: 4.19, H: 2.30).The modern high level ab initio calculations indicate that neon is surprisingly less reactive than helium. The reactivity order is Ne < He < Ar < Kr < Xe < Rn
How many electrons does an H plus ion have in the first shell?
The H+ ion has no electrons.

How many electrons are in their outer level?
Depends on the atom. Between one and eight electrons. There is a method to it. The elements on the very two first rows have one (H) and two (He). Over on the right side (Boron) of the elemental chart are three to eight electrons respectively.

Why does O2 bond with H if O2 has 8 electrons?
O2 is a molecule of a single nascent O (oxygen) atom . O has 8 electrons in all but only 6 electrons in its outermost shell - 2 electrons in its innermost kth shell.Now according to the octet theory the oxygen atom will be stable only if it has 8 electrons in its outer most shell because that is the shell responsible for a chemical reaction .so it shares 2 electrons, each from 2 hydrogen atoms to make a compound known as the universal solvent "water'.
