Concept Introduction :
Net charge of a molecule can be calculated by adding individual formal charges of each atom.
Formal Charge = Group Number − Number of lines − Number of dots
Group Number refers to the column number on the periodic table.
Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.
Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure.

- 27 Be sure to answer all parts. X 02:01:01 The following table gives numbers of electrons, protons, and neutrons in atoms or ions of a number of elements. Atom or Ion of Element Species A Species B Species C Number of Electrons 9 10 18 Number of Protons 9 19 Number of Neutrons 10 20 (a) Which of the species are neutral? A B C (b) Which are negatively charged? (c) Which are positively charged?arrow_forwardon dhe fepresentation of the periodic table below, Draw 2 arrows (next to and below) to represent increasing atomic radius. Electronegativity 1. How does electronegativity change as you move from left to right across a period? Explain your answer in terms of the number of protons in the nucleus. 2. Are there any exceptions to the trend in electronegativity as we move from left to right across a period? If so, explain what the exception is and why you think this occurs. 3. How does electronegativity change as you move from top to bottom in a group? Explain your answer in terms of energy levels.arrow_forwardWhat is the relationship between the number of hydrogens in an acid and the charge on the anion that they are combined with?arrow_forward
- Many common ionic compounds contain ions that are themselves composed of a group of covalently bonded atoms with an overall charge. True or false? Give some examples?arrow_forward1. Write formulas and names for compounds formed by the following positive and negative ions: a) Ba2+ and NO3- b) Al3+ and CO32- c) Pb2+ and CO32- 2. Write the cation and anion formulas (including charges) and the name of the following ionic compounds. (Use Roman numerals to indicate the charge on metals that can have more than one positive charge.) a) CaF2 b) TiO2 c) FeSO4 d) FeP e) NH4NO3 (this compound is composed of two polyatomic ions.) 3. Write formulas of the two ions in each compound and then write the formula of the compound. a) potassium iodide cation: K+ inputted as K^+ anion: I- inputted I^- formula: KI b) aluminum hydroxide c) sodium phosphate d) sodium phosphide e) copper(II) sulfidearrow_forwardAs seen in the table, compounds containing an integer ratio of elements depend on how many cations combine with how many anions to form a stable compound. For example, in table 1, to form a NaCl compound, first Na ionizes from the Na+ cation which is having +1 positive charge, which will lose 1 electron, it is having +1 charge, this electron then goes to Cl and it will change to Cl- anion by gaining the electron, so here 1:1 ratio charge which means 1 Na+ combines with 1 Cl-1 to form NaCl. So here integer ratio is 1:1 for this sodium chloride compound. As listed in table 2, Mg(OH)2, the integer ratio is 1:2 which means, Mg is a neutral atom that loses 2 electrons and forms an Mg+2 cation, which combines with OH which gains 1 electron to form OH- anion, So here Mg2+ can combine with 2 OH- anion, so they both combine to form Mg(OH)2 which has integer ratio as 1:2 . Thus, atom forms as ions by losing or gaining electrons and combines together in whole number ratio to form stable…arrow_forward
