Atomic mass is an atoms number of what?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
What is the mass of chlorine-35 relative to carbon-12?
The nucleon numbers 35 and 12 represent the relative isotopic mass of the isotopes. So, chlorine-35 is about three times heavier compared to carbon-12. You can see all the (average) atomic masses of the elements in the periodic table.
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
When the repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
Are elements organized by atomic weight and physical properties?
Elements are scientificaly organised according to their Proton numbers. Those with smaller proton numbers come first.
How many protons make up nitrogen-15?
It still has 7 protons because isotopes of elements have variable NEUTRON numbers, not nucleon (atomic mass) or proton numbers.
Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
What is the atomic mass number of an isotope?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
Atomic mass is an atoms number of what?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
Does oxygen -16 and oxygen -18 have different mass numbers?
The numbers 16 and 18 is their nucleon number. Hence, they will have different masses since they have different number of neutrons.
What is the mass of chlorine-35 relative to carbon-12?
The nucleon numbers 35 and 12 represent the relative isotopic mass of the isotopes. So, chlorine-35 is about three times heavier compared to carbon-12. You can see all the (average) atomic masses of the elements in the periodic table.
Which numbers are added to give the nucleon number of an ion?
No need to add. Use the elemnts mass number, which is the number of protons plus the number of neutrons
Are two numbers of 1 called elements?
two numbers with a product of 1 are called elements
Why are there numbers declining?
What numbers are you talking about? This question needs additional information.
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
What do different elements have different numbers of?
Different elements have different numbers of protons. The number of protons identifies the element.
What elements have atomic number?
All chemical elements have atomic numbers.
