2. ### If helium boils at about 4 K. What is this temperature in °C? What is this temperature in °F?

(1) T/K = (T/°C) + 273.15. Therefore 4 K = –269.15 °C (2) T/F = 9/5(T/°C) + 32. Therefore –269.15 °C = –452.47 F

5. ### which pair of elements is most likely yo form an ionic bond?

K and Cl and also K and C because in these pairs we have metal and non metal but the second pair is marginally ionic because the electronegativity difference is close to 1.7 the limit for having an ionic compound.

6. ### The ion K+ is formed by which process A) loss of an electron by K B) gain of proton by K C) loss of a proton?

It is impossible for an atom to gain or lose a proton naturally. K+ is positive, which means that it lost one negative charge (electron).
