是不是沒(méi)有中子的原子就沒(méi)有核素
是的,沒(méi)有中子,就沒(méi)有同位素概念。
1、同一種元素的所有原子中,只是各原子中,具有相同的質(zhì)子;
而可以有不同的質(zhì)子數;
.
2、質(zhì)子數加中子數之和,稱(chēng)為核子數;因此,
同一種元素的不同的同位素,具有不同的核子數。
.
3、核素,nuclide,是指具有相同的核子數的不同元素。
也就是說(shuō),核數只是指質(zhì)量數相同而已。
.
所以,
A、如果沒(méi)有中子,就沒(méi)有同位素;
B、沒(méi)有了同位素,原子的質(zhì)量數,就僅僅由質(zhì)子數確定;
C、不同的質(zhì)子數,就是不同的元素;
D、所有的元素的質(zhì)子數都不相同,就不可能出現不同的元素卻有著(zhù)
相同的質(zhì)子數的事情。也就是說(shuō),沒(méi)有了中子,就沒(méi)有核素概念。
是不是沒(méi)有中子的原子就沒(méi)有核素
是的。沒(méi)有中子的原子就沒(méi)有核素。
核素是指具有一定數目質(zhì)子和一定數目中子的一種原子.例如,原子核里有6個(gè)質(zhì)子和6個(gè)中子的碳原子,質(zhì)量數是12,稱(chēng)為碳-12核素,或寫(xiě)成12C核素.原子核里有6個(gè)質(zhì)子和7個(gè)中子的碳原子,質(zhì)量數為13,稱(chēng)13C核素.氧元素有16O,17O,18O三種核素.具有多種核素的元素稱(chēng)多核素元素.自然界僅有一種核素存在的元素稱(chēng)為單核素元素,如氦、氟、鋁、鈉等20種元素.質(zhì)子數為偶數的元素,可有較多的穩定核素,一般不少于3種,而質(zhì)子數為奇數的元素,通常只有一個(gè)穩定核素,從不會(huì )多于兩種,這是由核子的結合能所決定的.多核素元素中各核素互稱(chēng)同位素,因為它們處于周期表中同一位置上,化學(xué)性質(zhì)基本相同,但核性質(zhì)不同;單核素元素沒(méi)有同位素.核素的質(zhì)量即原子質(zhì)量,總小于孤立質(zhì)子、中子和電子的質(zhì)量總和,在概念上也不等于質(zhì)量數,在數值上除12C外均與質(zhì)量數稍有不同.核素的質(zhì)量是用質(zhì)譜儀測定的,這種測定很先進(jìn),可測得7位或更多位有效數字
