What else can I help you with?
When Mendeleev published his periodic table there were some spaces for undiscovered elements Figure 15-1 is a section of a similar table A reasonable value for the atomic mass of the missing element?
A reasonable value for the atomic mass of the missing element can be estimated by finding the average atomic mass of the elements on either side of the missing element in the periodic table. This estimation assumes a gradual increase in atomic mass across the periods in the table.
How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
Can you find the atomic number of an element on the periodic table?
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
What element on the periodic table weighs 19.32?
No element has an atomic weight of 19.32 on the periodic table.
What does the atomic munber mean on the periodic table?
The atomic number on the periodic table represents the number of protons in an atom's nucleus. It determines the element's identity and its position on the periodic table. Each element has a unique atomic number.

What is the atomic number of Periodic Table element Period?
The atomic number of the Periodic Table element Period is 92.
What is the atomic number of the element lanthanum on the periodic table?
The atomic number of the element lanthanum on the periodic table is 57.
What element on the periodic table has the largest atomic number?
The element with the largest atomic number on the periodic table is Oganesson, with the atomic number 118.
What is the atomic number on the periodic table?
The atomic number on the periodic table is the number of protons for the element.
How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
Was the first element on the periodic table of elements carbon?
NO!!! Hydrogen (H) is the first element on the Periodic Table. Reason Atomic No. = 1 Atomic mass( of protium) = 1 Carbon lies 6th position. Atomic No. = 6 Atomic mass = 12
What is the atomic number of the element with the symbol "Pt" on the periodic table?
The atomic number of the element with the symbol "Pt" on the periodic table is 78.
What is the atomic number of an element listed in the Periodic Table refers to?
The atomic umber of an element listed in the periodic table refers to number of protons in the element. Atomic number is equal to number of protons.
Can you find the atomic number of an element on the periodic table?
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
What element on the periodic table weighs 19.32?
No element has an atomic weight of 19.32 on the periodic table.
Is the atomic number of each element included in the periodic table?
YES!!! The atomic No. is the postition of the element in the periodic table. It also indicates the number of protons in the element and electrons in the neutral element. The Atomic Mass is also included in the periodic table. The Atomic Mass is the sum of all the protons and neutrons of an element in the periodic table. Here are some examples. Hydrogen ; [1/1]H The first element in the table Carbon ; [12/6]C The sixth element in the periodic table Oxygen ; [16/8]O The eighth element in the periodic table et.seq., The first number given is the Atomic Mass and the second number is the Atomic Number.
