What elements does lithium resemble (in terms of electrons) when it loses 1 electron?

Chemistry
1 answer:
tigry1 [53]2 years ago
5 0

Answer:

Li atoms readily give up one electron to form positively charged, Li+ ions. These ions have the same stable electron configuration as the noble gas helium. All Group 1 atoms can lose one electron to form positively charged ions.

Identify the compound with the highest magnitude of lattice energy. Identify the compound with the highest magnitude of lattice
Galina-37 [17]

Answer: Option (c) is the correct answer.

Explanation:

According to the Born-Lande equation,

          E = \frac{N_{A}Mz^{+}z^{-}e^{2}}{4 \pi \epsilin_{o} r}

where,   N_{A} = Avogadro's constant

                    r = distance between the anion and cation

                   M = Medlung constant

           z^{+} = charge on the cation

           z^{-} = charge on the anion

                  E = lattice energy

According to this expression, lattice energy is inversely proportional to the distance between the cation and anion. And, when we move down a group then there occurs an increase in the atomic radii of the atoms.

As a result, there will occur a decrease in their lattice energy. Since, the anionic part is same in all the given species but the cationic part is different.

In MgBr_{2} the size of magnesium cation is smaller than calcium, barium and strontium ion. Hence, there will be least distance between Mg and Br ions.

Thus, we can conclude that the magnitude of lattice energy will be the highest in MgBr_{2}.

State the number of sig figs in each value:
Rasek [7]

Answer:

Explanation:

Significant figure implies number of digits that are to be considered. Some rules are required to be considered when writing a given expression to an expected significant figures.

So that:

1) 0.00004050 is 4 significant figures

2) 54.7000 is 6 significant figures

3) 1,000.09 is 6 significant figures

4) 0.039 is 2 significant figures
