It depends on the species.
There are quite a few websites, for example http://bulbapedia.bulbagarden.net or http://serebii.net , that list information about Pokémon, including when they level up, so you can look up each species/family there.
Some Pokémon do not evolve at a certain level, but need other conditions, such as a high Happiness score or levelling up at a certain time of day and/or holding a certain item, but you can find that for any species of Pokémon individually if you look for it online.
There are some Pokémon that cannot evolve such as Hitmonlee, Hitmontop, Raichu, Hitmonchan and Blissey however the Pokémon that can evolve they can evolve at various levels such as Pikachu being able to evolve at any level since it will evolve through the use of a Thunder Stone, Magma and Elekid will both begin to evolve at Level 30 into Magmar and Electabuzz respectively, Graveler and Kadabra can evolve at any level due to needing to be traded before they can evolve and Pokémon such as Dratini can first start to evolve at Level 30 and it will evolve into Dragonair and then Dragonair can start to evolve into Dragonite at Level 55.
There are some Pok
Buizel evolve at level 26.
Arbok does not evolve
Rare candies only raise a pokemon's level. There are no pokemon that need a rare candy to evolve. That being said, using a rare candy may elevate a pokemon to the level required for evolution.
They all evolve at different levels

Emolga does not evolve. I played Pokemon White also and it does not evolve. Some Pokemon do but this one does not evolve.
Be specific. What pokemon? ---------------------------------------- Most of them evolve at level 16 than level 36 :)
It evolves in Pokemon Diamond and Pokemon Pearl at Level 40.
Pikachu do not evolve by level. They evolve when a thunderstone is used on them.
Pokemon evolve at different levels so you never really know what level it is
Many Pokemon evolve at certain levels. Some don't even evolve with level!
At level 16. if you don't know how to evolve Pokemon then go to your Pokemon box with your level 16 Charmander and press evolve.
the level they ussually evolve.
it will evolve at level 21
It will evolve at level 48
You have to Level it up in Battles. Once you get to a certain level... It will evolve right after. Another way pokemon evolve is frienship, once there happiness level is high enough, and you level them up one more level they will evolve. The last way for Pokemon to evolve is with a stone. Few pokemon evolve from evolutionary stones, but when they do they evolve as soon as you use it on them.
Rephrase your question = What level does snorlax evolve on Pokemon diamond? =
