Artwork: Carbon-12 and carbon-14 are both isotopes of carbon: different variations that have different numbers of neutrons (blue). Carbon-14 has two more neutrons (yellow) than carbon-12, but both have six protons (red) and six electrons (green). Sponsored links How do atoms make ions?
Atoms with the same number of protons but different numbers of neutrons are called isotopes. Mass of isotopes Isotopes containing more neutrons have a greater mass. 具有相同质子数不同中子数的原子互为同位素。中子数多的同位素质量更大。 In spite of these differences, isotopes of an atom have the ...
Isotopes - isotope: atoms of the same element that have different numbers of neutrons - Carbon, as found in nature, is a mixture of isotopes, including atoms of carbon-12, carbon-13, and small amounts of carbon-14. Isotopes atomic weight - The atomic weight of an element is the weighted...

neutrons in an atom is often-but not always-thesame.Every element has a different number of protons.This helps make it differentfrom another element.An element's atomic number is the same as its number ofprotons.For example,hydrogen has only 1 proton.So this means thatit has an atomic ...
Atoms of the same element that have different numbers of neutrons (thus different mass #) Ion Atom that has a net charge because it has gained or lost electrons+ charge = less electrons- charge = more electronsnet charge = # protons - # electrons 最好的學習方式。免費註冊。 註冊代表你接受...
the sum of the number of protons and the number of neutrons in the nucleus of an atom. isotopes atoms of the same element that have different numbers of neutrons. average atomic mass the weighted average mass of all naturally occurring isotopes of an element. ...
Isotopes are the atoms of same element, they have same atomic number but different mass numbers. Isotopes have different number of neutrons in their nucleus . If an element exists in two isotopes having atomic masses 'a' and 'b' in the ratio m:n, then average atomic mass will bem×a+n...
So, in the above example of lead, its atomic number is 82 and that does not change; if it did, it would be a different element (thallium, atomic number 81, or bismuth, atomic number 83). The number of neutrons in the nucleus, as you may have gathered from the above example, can ...
Each element is made up of atoms that are composed of even smaller particles. The difference between one element and another is because of the difference in the number of protons in their atoms. However, some atoms of the same element have different numbers of neutrons; those different atoms ...
