The lightest simbi. Ndezvipi chiedza nesimbi?

The simbi rokutanga kuti murume zvakwakafukurwa, vaiva ndarama, mhangura uye sirivha. Vakanga yaishandiswa kare. Ndezvipi zvinhu izvi? Ndeupi simbi iri nyore?

simbi

Kokutanga vanhu akawana nesimbi kuti vari pedyo pemvura. Chokutanga chaiva mhangura, ndarama nesirivha, gare gare netini, simbi, nendarira uye kutungamirira. With kukura vanhu zvishoma nezvishoma kuwedzerwa pasi. Parizvino pane vanenge 94 simbi.

Idzowo nyore zvinhu kuti nhaka yakakwirira conductivity nokupisa kuchinjirwa, ductility, goho nokuchengetedza, vane maitiro esimbi kubwinya. Zvakasikwa, vanowanzoororwa akawanikwa ari muchimiro siyana yeimwe uye ores.

Unhu nesimbi kwoita ferrous, nonferrous uye anokosha. Kuzvishandisa aparadzana pesimbi, kuchenesa rinoitwa, alloying nezvimwe kugadzira. Metals vari chikamu zvipenyu aripo yomugungwa.

Mumuviri wedu, vari diki nhamba, kuita zvinokosha mabasa muupenyu. The chipo chiropa mhangura, karusiyamu - iri marangwanda uye meno, yavaibvisa - iri cytoplasm masero, simbi ndiyo chikamu ropa uye tsandanyama riri magnesium.

The lightest simbi

Mupfungwa vanhu vazhinji vakaramba mafungiro nesimbi somunhu simba, yakasimba uye rinorema zvokuvakisa. Vamwe vavo zvachose kukodzera kurondedzera. Pane zvinhu zvinoverengeka nesimbi kuti une simba shoma, uye aizorodzwa izvi zvinhu kutama. Vanogona kunyange kuyangarara pamusoro pemvura.

The lightest simbi munyika - lithium. At kamuri tembiricha, ayo arambe achirema iri rakadzika. Rinopa rinenge mvura kaviri uye 0,533 magiramu muzana cubic sendimita. Nokuda arambe achirema diki, izvozvo floats mumvura neparafini.

Lithium zvirimowo mugungwa mvura uye okumusoro Continental goko. Akawanda, kuti lightest simbi aripo ari akatisiyira chinhu Zvishavane-Zhitkova randinogara dzvuku hofori uye supergiant.

Under kwomuzvarirwo ezvinhu, lithium ndiyo ductile nyore kufurirwa silvery simbi, saka nyoro kuti rinogona kubviswa nebanga. Inonyunguduka pa 181 Celsius. Hazvina chepfu uye kushingaira interacts pamwe zvakatipoteredza, saka haasi kushandiswa kwayo yakachena chimiro.

aruminiyamu

Mushure lithium ndiyo lightest simbi - aruminiyamu, uyezve, zviri vafuke chaizvo. Nokuda zvakawanda kushandiswa muminda siyana, iye akawana musoro "simbi yacho XX remakore". Munguva cortex, nyika iye wechitatu inonyanya chinhu pakati vokutanga simbi.

Aluminum ane sirivha-chena, ane mukuru ductility, uye chafariz conductivity. It anokwanisa nokuumba alloys pamwe anenge chero simbi. Zvinowanzoshandiswa pachiimbwa magnesium uye mhangura. alloys zhinji vakasimba kupfuura simbi.

Aluminum havaratidzi amenable kusimbisa ngura nokuda paumbwe oxide mafirimu. Iye mamota panguva tembiricha kuti 2500 Celsius. Chinhu simba paramagnetic. Yezvakaita simbi huri muchimiro yeimwe, zvinokosha ayo anowanikwa chete kashoma mune dzimwe kuputika vent.

piece keke

Mikrolattis - the lightest simbi yakabereka artificially. Inoitwa mhepo pa 99,99% uye zviri nyore kuti furo. Metal akasikwa nemasayendisiti paUniversity of California, muna 2016 zvakanzi pamutemo uye rave akanyorwa muna Guinness Book of Records.

The chakavanzika kujairika vakasununguka ayo mamiriro akafanana pfupa zvipenyu. Metal chinhu sero tinoitirwa kubva nickel-phosphorous sepombi. Vane husina uye ukobvu yavo kanoverengeka asingasviki sebvudzi romunhu.

Pasinei kudekara mikrolattis anokwanisa withstanding inorema kupfuura zvepanyama simbi. ehupfumi kwakadaro kunogona kushandiswa nevakawanda, mumwe wavo - ndiko kusikwa chakagadzirwa chiedza.
