The atomic number of an atom of an element is 17 while its mass number is 35. How many neutrons does the atom have? The atomic number of an element gives the number of and in the atom while the mass number gives
An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom?Atomic and Mass Numbers:The atomic number of an atom is equal to the number of protons found in the atom's nucleus. The mass number of an atom is the total number...
1 atomic mass unit is equal to 01:49 The mass of an atom depends upon the number of 02:27 The mass of neutron is same as that of 01:38 Masses of many atoms are close to integral multiple of the mass of an 02:14 The ratio of the mass of the proton to the mass of the electro...
To find the atomic mass of chlorine based on its isotopes, we can follow these steps:Step 1: Identify the isotopes and their atomic masses Chlorine has two isotopes: - Isotope 1: Atomic mass = 35 u - Isotope 2: Atomic mass = 37
这里主要取决于 the mass of这个词组里的the，虽然意思为“大量的”，但它后面的名词接的是单数形式，但如果是a mass of其后就接的是复数名词了！mass
这句话的意思是 “为了测量原子的质量,科学家采用了原子质量单位(amu)” 。从语法角度来看,“To measure the mass of an atom” 是动词不定式作目的状语,表示目的,“scientists” 是主语,“adopted” 是谓语,“amu” 是宾语,句子结构完整,语法正确。从语义角度,在科学领域,科学家确实采用原子质量单位(amu)来测量...
3 CHEMISTRY-RELATIVE ATOMIC MASS the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atom, so its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24 再给另一个例子 不要用英文...
