         <description><![CDATA[<div>원소 기호:Li<br>원자 번호:3번<br>원소 특징:리튬은 원자번호 3번의 원소로 원소기호는 Li이다. 주기율표에서 알칼리 금속족(1족)에 속하며, 은백색 금속이다. 금속 중에서 가장 가볍고 고체 원소 중에서는 밀도가 가장 낮다. 다른 알칼리 금속과 마찬가지로, 물, 산소와 잘 반응하며 자연 상태에서는 화합물로만 존재한다. 현대 우주론에 따르면, 우주 생성의 대폭발(빅뱅) 때 수소, 헬륨과 더불어 생성된 원소이나, 핵의 안정성이 크지 않아 대부분 파괴되어 현재 지각에서의 존재량은 무게 비로 단지 0.002~0.007%일 뿐이다. 칼로 자를 수 있을 정도로 무르나, 알루미늄이나 마그네슘과의 합금은 매우 가볍고 강하여 항공기 부품 재료로 이용된다. 냉전 시대에는 수소 폭탄 제조와 연관하여 큰 관심을 끌었다. 20 세기 후반부터 높은 에너지 밀도를 갖는 리튬 전지와 리튬 이온 2차 전지의 양극 물질로 사용되어 휴대용 전자 제품의 혁신을 가져왔으며, 전기 자동차의 대중화를 위한 필수적인 원소가 되었다.</div>]]></description>

         <description><![CDATA[<div>원소 기호: Cu<br>원자 번호: 29<br>원소 특징: 구리는 11족에 속하는 금속이다. 또한 전기 전도성이 모든 금속 가운데 2번째로 높으며, 전성과 연성이 높아 현재의 정보화 시대에 큰 기여를 한 물질 중 하나다. 산성이나 염기성에 대한 내성과 열전도율이 매우 높은 것도 특징이다. 구리는 아연(Zn)의 합금인 황동으로 많이 쓰이지만 공기 중에서 산화가 될 수 있다. 구리는 금(Au)나 은(Ag)에 비하면 꽤 싸지만 비교적 흔한 금속 중에 비싼 편에 든다.</div>]]></description>
