Answer:

When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge

Describe the steps used to create Lewis dot structures to represent covalent bonds.
antiseptic1488 [7]
1)Identify the atoms that are participating in a covalent bond.
2)Draw each atom by using its element symbol. The number of valence electrons is shown by placing up to two dots on each side of the element symbol, with each dot representing a single valence electron.
3)Predict the number of covalent bonds each atom will make using the octet rule.
4)Draw the bonding atoms next to each other, showing a single covalent bond as either a pair of dots or a line representing a shared valence electron pair. If the molecule forms a double or triple bond, use two or three lines to represent the shared electron pairs, respectively.

How many atoms of N are in 137.0 grams of N2O3?
olasank [31]

Answer: The number of N atoms in 137.0 g of N2O3 21.67 x 10∧23 atoms.

Explanation:

  • We must obtain the number of moles of the compound: (n = mass/molar mass), mass = 137.0 g and molar mass of N2O3 = 76.01 g/mol.
  • n = (137.0 g)/ (76.01 g/mol) = 1.80 mol.
  • It is necessary to determine the number of molecules of this sample.
  • Every mole contains Avagadro's number (6.02 x 10^23) of molecules.
  • The number of molecules = (6.02 x 10^23)(1.80) = 10.84 x 10∧23 molecules.
  • Every molecule of N2O3 contain 2 atoms of N.
  • The number of N atoms in 137.0 g of N2O3 = (10.84 x 10∧23 molecule) (2 atoms) = 21.67 x 10∧23 atoms.
