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
Three elemnts named after countries?
Americium, Francium, Polonium
What is th oxidation number of phosphorus in red phosphorus?
Zero- red phosphorus is an allotrope of phosphorus, a form of the element. By definition elemnts are considered to be neither oxidised or reduced.
What is the oxidation number for CH3F?
H is +1, F is -1, therefore C is -2 ( the sum of the oxidation numbers of the elemnts in an electronically neutral atom is defined as zero)
If a balloon contains 0.15 moles of CO2 gas. how many molecules of CO2 are in the balloon?
The number of molecules is 0,90332112855.10e23.
How amny elemnts are there in CO2?
Carbon dioxide contain carbon and oxygen.
What is the periodic table rows and columns for?
The columns organise the elemnts according to the number of valence electrons that give rise to many of the similarities between the chemistry of the elemnts in the column. The rows organise in increasing atomic number.
Does the number of neutrons vary for a single element?
Yes. The number of neutrons determines the various isotopes of the elemnts.
What is the oxidation number for the H element?
Zero. the oxidation number of all elemnts in every form is zero
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
What is the atomic number for CO2?
CO2 does not have an atomic number as it is a compound. Only elements have atomic numbers.
How many elemnts in NH4NO3?
9
What does np stand for on the periodic table of elemnts?
Np stands for the element neptunium.its atomic number is93 and atomic weight is 273
What is the number of molecules of CO2 in 1 grams?
CO2's molecular weight is 44 so 44 g of CO2 contain Avogadro's number of CO2 molecules. 20 g would contain 20/44 x Avogadro's number.
Many elemnts found in nature exists as?
...as a solid.
How many atoms is 110 grams of CO2?
After figuring out the calculations using the weight of CO2 and Avogadro's number, the total number of atoms in 110 grams of CO2 is 2.34 X 10^18 in sum.
2 elemnts present in methane?
Carbon and hydrogen, CH4
