How do you know how to find the atomic number on the periodic table?
Its directly under the Symbol. Example: ___________ 1 <--- atomic number 1.008 <--- atomic weight Hydrogen <--- element name ____________
What is the name of the two numbers assigned to every element on the periodic table?
Atomic number (protons) and atomic mass (not to be confused with atomic weight, even if the difference is slight)
What is the name of the element with the atomic number 54?
The name of the element with the atomic number 54 is Xenon (Xe).
What is the name of the element that has an atomic number of 3?
The name of the element that has atomic number 3 is Lithium (Li).
What is the name of the element with atomic number 70?
Ytterbium (Yb) is the name of the element with the atomic number 70.
What does the periodic table contain?
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
What is the relative atomic mass of argon?
(Symbol Ar) / Atomic weight 39.948
What is the name of the element in the periodic table that is dedicated to Dimitri Mendeleev's work?
