Answer:
Methane + Bromine = (CH4+Br2)
Explanation:
When a mixture of methane and bromine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is bromomethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by bromine atoms. The reaction is a single-step reaction.
Answer:
When an ionic crystal breaks, it tends to do so along smooth planes because ... ions are forced near each other and the repulsive force causes the crystal to shatter. ... Cations move to one electrode, while anions move to the other, ... Diagram of ions in an ionic solution when an electrical current is applied.

The majority of their bonds are nonpolar covalent carbon-to-hydrogen linkages.

Explanation:
9) If an extra electron is added to the neon atom, then the electronic configuration becomes; 1s2 2s2 2p6 3s1
This last electron has quantum numbers;
n=3, l=0, m=0 and s = +1/2
This is so because the 2s level is already filled so the extra electron must go into the 3s level. The orbital quantum number and the magnetic quantum number for the s orbital is zero.
10) Electron affinity is the energy released when one mole of gaseous atoms accept one mole of gaseous electrons to form one mole of gaseous ions having a negative charge.
In the second period, fluorine has the greatest electron affinity since electron affinity increases across the period. The noble gas, neon has an electron affinity of 0KJ/mol.
11) Ionization energy decreases down the group but increases across the period due to increase in the size of the nuclear charge and decrease in the distance between the nucleus and the outermost electron. Hence, the process; Br+(g) ---->Br2+(g) + e- has the greatest ionization energy. Recall that the second ionization is always higher than the first ionization energy.
12)The order of decreasing metallic character here is K> As> P. Even though As and P belong to the same group, we must note that metallic character increases down the group hence the order written above.
