Give the brainliest Classify the following metals by increasing order of melting temperature
a) Na Li K
Classify the following metals by increasing order of melting temperature
b) Al Mg Na

Explanation:

a. K Na Li

melting point decreases a

down the group since more shells are added down the group hence the the attractive force that the protons exert on the electrons decreases down the group and hence melting point also decreases down the group.

i.e Li,Na,K decreasing order.

And hence the increasing order will be:

K Na Li.

b. Na Mg Al

Effective nuclear charge increases across the period and hence melting point increases across the period since Al Mg and Na are in the same period hence the increasing order will be Na Mg Al.

thats how its supposed to be

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
