What else can I help you with?
What mostly fills the periodic table?
The periodic table of the elements is filled mostly with metal elements.
Each row in the periodic table ends when an outer energy level is what?
filled. That would be 2 electrons for helium, and 8 electrons for the rest of the noble gases in group 18 on the periodic table.
Why does the periodic table end with a noble gas?
because they have completely filled orbitals
What are elements and the periodic table?
An element is a substance that cannot be broken into simpler substances by chemical methods, such as Neon or Oxygen.The periodic table contain all known chemical elements.
What are the exceptions for ionization energy in the periodic table?
Exceptions to the general trend of increasing ionization energy across a period in the periodic table occur when there is a half-filled or fully-filled subshell, which results in increased stability and lower ionization energy. This is known as the "half-filled and fully-filled subshell stability" rule.
What eventually happened to the gaps left in the periodic table left by Mendeleev?
The gaps in the periodic table left by Mendeleev were eventually filled in as new elements were discovered. Scientists continued to study and experiment, leading to the discovery and verification of elements that fit into the empty spaces in the periodic table.
Father of the periodic table?
Dmitri Mendeleev is known as the father of the periodic table. He developed the periodic table by arranging elements based on their atomic mass and chemical properties, establishing the foundation for the modern periodic table used today. Mendeleev's table had gaps for undiscovered elements, which were later found and filled, validating his organization of the elements.
Can you identify the d-block element in the periodic table?
The d-block elements in the periodic table are located in groups 3 to 12. They are transition metals that have partially filled d orbitals.
Why was leaving spaces and gaps in the periodic table later vindicated?
Leaving spaces and gaps in the periodic table allowed for prediction of new elements and their properties, which were later discovered and filled in. This vindicated the decision to leave gaps, as it demonstrated the power of the periodic table in organizing and predicting the properties of elements.
On the periodic table what tells you which subshell of an atom is being filled?
The period number on the periodic table tells you which energy level (shell) of an atom is being filled. The subshell within that energy level is determined by the block in which the element is located on the periodic table. For example, elements in the s-block fill the s subshell, elements in the p-block fill the p subshell, and so on.
The elements in the periodic table that have a completely filled outer subshell are known as?
noble gases.
What does d stand for on the periodic table?
In the periodic table, 'd' refers to the blocks of elements in the d-block, which includes transition metals. These elements have partially filled d orbitals in their electron configurations.
