Ответ:

1-Первым металлом, с которым познакомился человек, было золото. Это произошло еще в эпоху каменного века. Дело в том, что таким металлом может быть только самородный металл. А золото нередко встречается в виде золотых самородков. Метеоритное железо встречается значительно реже. Кроме того, золото - мягкий пластичный металл, а обрабатывать тугоплавкое железо (оно плавится на 500 градусов выше, чем золото) древние люди еще не умели. Ртуть же нужно еще извлекать из породы, в которой она встречается в виде мельчайших капелек. И такие породы встречаются довольно редко. А обжигать ртутный минерал киноварь и конденсировать получающиеся при этом ртутные пары еще нужно было научиться. -
