The Lewis Dot structure for NaBr consists of Na with one valence electron and Br with seven valence electrons. The Na atom will transfer its electron to the Br atom to form an ionic bond, resulting in Na+ and Br- ions.
The Lewis structure for Helium is He with two dots next to each other, above the He symbol. The dots must be drawn next to each other, they represent the two electrons found in the 1s-orbital of the Helium atom.
The Lewis dot structure of AsCl5 consists of an As atom surrounded by 5 Cl atoms. Since As has 5 valence electrons and each Cl atom contributes 7 valence electrons, a total of 40 valence electrons are used in the structure with multiple bonds formed to fulfill the octet rule.
The Lewis Dot symbol for Thorium (Th) can be represented as Th with two dots above it to indicate the two valence electrons in the outer shell. Thorium is a member of the actinide series in the periodic table and belongs to Group 3. Its electron configuration is [Rn] 6d2 7s2, indicating the placement of its 90 electrons in the various energy levels.
The flouride ion (F-) has 8 electrons. I can't really draw it with text, but it has 4 pairs of electrons arranged around it a bit like this... .. :F: '' The top and bottom pairs need to be directly above/below the 'F'
The Lewis structure for krypton (Kr) has 8 electrons around the symbol, representing a noble gas configuration. Radon (Rn) is in the same group as krypton but has 6 valence electrons, creating a different arrangement in its Lewis structure with 2 lone pairs above and below the Rn atom.
The Lewis Dot structure for NaBr consists of Na with one valence electron and Br with seven valence electrons. The Na atom will transfer its electron to the Br atom to form an ionic bond, resulting in Na+ and Br- ions.
The Lewis structure for Helium is He with two dots next to each other, above the He symbol. The dots must be drawn next to each other, they represent the two electrons found in the 1s-orbital of the Helium atom.
The Lewis dot structure of AsCl5 consists of an As atom surrounded by 5 Cl atoms. Since As has 5 valence electrons and each Cl atom contributes 7 valence electrons, a total of 40 valence electrons are used in the structure with multiple bonds formed to fulfill the octet rule.
The correct Lewis Structure for the oxygen atom will be an 'O' with two dots above and below, with one dot on the left and on the right sides.
none of the above. or all of the above for plato!
The Lewis Dot symbol for Thorium (Th) can be represented as Th with two dots above it to indicate the two valence electrons in the outer shell. Thorium is a member of the actinide series in the periodic table and belongs to Group 3. Its electron configuration is [Rn] 6d2 7s2, indicating the placement of its 90 electrons in the various energy levels.
Lead sulfate (PbSO4) is an ionic compound. It consists of a lead ion (Pb2+) and a sulfate ion (SO42-) bound together in an ionic bond. The structure of the sulfate ion is a sulfur atom surrounded by 4 oxygen atoms.
The flouride ion (F-) has 8 electrons. I can't really draw it with text, but it has 4 pairs of electrons arranged around it a bit like this... .. :F: '' The top and bottom pairs need to be directly above/below the 'F'
The dot structure for bromine dioxide starts with a Br atom in the center. To the left and right is a singly bonded O atom, each with a pair of dots on the three unbonded sides. The Br atom has a pair of dots on the upper and lower unbonded sides.
~ .. .. H:O:Cl: ~ .. .. This is incorrect. Hydrogen my only have two electrons to fill it's outer shell. Where as Oxygen and Chlorine prefer eight electrons. The formating on this program does not allow lewis dot structures to be drawn correctly. However the answer is H:O:Cl with another pair of electrons above and below oxygen and again above and below Cl. (like above except with out the ~'s)
I -> 7e- O(3x) -> 3(6e-) = 18e- Since its an IO3- it has an extra electron Total electrons = 18e- + 7e- +1e- = 26e- I is the Central Atom Each O has a single bond with 6 valance electrons and I and 2 Structure : Trigonal Pyramidal
