(a)
Interpretation: Using Lewis dot symbol the transfer of electrons between the given atoms to form cations and anions has to be shown.
Concept Introduction: Lewis dot symbol is used to represent the valence electrons of an atom or ion using dots surrounding the element symbol along four sides of the element symbol without maintaining exact order for the placement of dots.
In Lewis dot symbol representation, the
The valence electron is the number of electrons present in the outermost shell of the atom. The number of valence electrons will be same for the same group elements which is represented by Lewis dot symbol.

Concept Introduction: Lewis dot symbol is used to represent the valence electrons of an atom or ion using dots surrounding the element symbol along four sides of the element symbol without maintaining exact order for the placement of dots.
In Lewis dot symbol representation, the symbol of element is surrounded by "dots" indicating the number of valence electrons available for the element. The dots can be placed one at a time on all the four sides, further electron can be placed by pairing up with the first placed dots. According to the number of electrons added or removed, charge must be placed on the Lewis dot symbol for cations and anions.
The valence electron is the number of electrons present in the outermost shell of the atom. The number of valence electrons will be same for the same group elements which is represented by Lewis dot symbol.

- Based on Linus Pauling's electronegativity scale, would H2S be considered a polar molecule? Pick the best answer. (a) No. It would technically be considered a non-polar molecule. (b) No. Even though it contains polar bonds they are symmetrical and therefore H2S is non-polar. (c) No. The electronegativity difference between H and S is so great that it would be considered an ionic compound. (d) H2S violates the octet rule and therefore would not even existarrow_forwardWrite the empirical formula of at least four binary ionic compounds that could be formed from the following ions: 2+ Mg", Au*", I, o²- 0,0,..arrow_forward3.

- A resident expert on electronegativity comes up to visit with you. He makes two claims (seen below) about electronegativity with relation to covalent bonding. Is the expert correct or can you refute him with your knowledge of electronegativity? (a) If a diatomic molecule is made up of atoms X and Y, which have different electronegativities, the molecule must be polar. (b) The farther two atoms are apart in a bond, the larger the dipole moment will be.arrow_forwardAnswer true or false. (a) The octet rule refers to the chemical bonding patterns of the first eight elements of the Periodic Table. (b) The octet rule refers to the tendency of certain elements to react in such a way that they achieve an outer shell of eight valence electrons. (c) In gaining electrons, an atom becomes a positively charged ion called a cation. (d) When an atom forms an ion, only the number of valence electrons changes; the number of protons and neutrons in the nucleus does not change. (e) In forming ions, Group 2A elements typically lose two electrons to become cations with a charge of 12. (f) In forming an ion, a sodium atom (1s22s22p63s1) completes its valence shell by adding one electron to fill its 3s shell (1s22s22p63s2). (g) The elements of Group 6A typically react by ac- cepting two electrons to become anions with a charge of 22.
