How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What do isotopes' differences depend on?
Isotopes depend of the number of neutrons in the nucleus. The number of protons will always remain the same for that particular element. The number of neutrons may vary because they do not affect the charge, but rather its weight. This is why we have peculiar numbers for the average atomic mass, because some elements have different isotopes and based on how common they are will affect its average atomic mass.
How many electrons do you need to become a noble gas?
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
Which periodic table number determines which element an atom is?
An atom's atomic number tells which element it is. The atomic number of an element is equal to its number of protons. The number of neutrons may vary within an element, giving rise to the concept of isotopes.
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass of isotopes is not a whole number.
How may neutrons does neon have?
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
Is the number of neutrons equal to the atomic number?
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
What is the relationship between the atomic number and the atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
What particle has a zero electric charge?
1. photon has zero charge.there may also be sub atomic particle with zero charge.
What is the electrical charge of the chlorine ion?
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
What is the atomic symbol for hydron?
Hydron is the name of cation of Hydrogen. Thus the atomic symbol is H+. The name Hydron may also include the cations of the isotopes of hydrogen. D+ and T+ are also hydrons of Deuterium and Tritium respectively.
Any element can always be identified by its?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
When an atom becomes a cation what happens to it's radius?
The atomic radius of a cation is smaller than that of its original atom. See the related link for an image example of what this may look like.
What do isotopes' differences depend on?
Isotopes depend of the number of neutrons in the nucleus. The number of protons will always remain the same for that particular element. The number of neutrons may vary because they do not affect the charge, but rather its weight. This is why we have peculiar numbers for the average atomic mass, because some elements have different isotopes and based on how common they are will affect its average atomic mass.
