Elements 89-100 are the Actinide series of elements, most of which are radioactive, and some of which can only be made artificially. Elements 81-88 are also likely to be radioactive, but are naturally occurring.

Where are the atomic numbers of an atom on the Bohr diagram?
The atomic numbers are the numbers of protons in the nucleus of atoms, so they are placed in the nucleus of a Bohr diagram.
What is the atomic number for CO2?
CO2 does not have an atomic number as it is a compound. Only elements have atomic numbers.
What are the two criteria that are responsible for the arrangement of the periodic table?
The elements in the modern periodic tables have been arranged on the basis of their atomic numbers.
Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
What is 81103 rounded to the nearest hundred?

What is 81100 as a decimal?
81,100
What element has the atomic number for 3.14?
No element has this atomic number. All atomic numbers are whole numbers.
How do you write 81100 as percentages?
