What else can I help you with?
What do elements in the same periodic. Have in common?
They have the same number of occupied energy levelsthey all have the same amount of outer shells for the atom
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
What element would have a full valence shell on the periodic table?
The noble gases helium and neon are the only elements with completely full outer shells.
What are nobles gas?
The nobles gases are the elements located on the very right of the periodic table. The elements are Helium, Neon, Argon, Krypton, Xenon and Radon. The common thing with the noble gases is that they have full outer shells, and don't react with any elements.
Where on the periodic table are you most likely to find elements that do not react with other elemets?
Elements that do not react with other elements are typically found in the noble gases group, located in Group 18 of the periodic table. These elements have full outer electron shells, making them stable and unlikely to form chemical bonds with other elements.

What elements have outer shells?
protons

Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.
What does the period number tell you?
It tells you the number of cations in the outer energy level of the element's atomic mass
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).

What element would have a full valence shell on the periodic table?
The noble gases helium and neon are the only elements with completely full outer shells.
What are elements with full outer electron shells called?
Elements with a full outer electron shells are usually found in group 18/8 on the periodic table, also known as 'Noble Gases'. But during a chemical reaction the element may gain or lose electrons in order to become stable. These atoms are called 'Ions'
What do the elements in column 18 of the periodic table have in common?
The elements in column 18 of the periodic table, also known as the noble gases, all have a full outer electron shell, making them stable and unreactive. This is because their outer shell is filled with electrons, so they do not typically form chemical bonds with other elements.
