How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
When atoms become ions their outer most shells of electrons become?
they add or loose electrons from the outer most shells
What elements have outer shells?
protons
How do the inner electron shells differ from an atom's outer electron shells?
Inner electron shells are closer to the atomic nucleus and have lower energy levels compared to outer electron shells. Outer electron shells are farther from the nucleus and have higher energy levels, making them more involved in chemical reactions and bonding with other atoms.
Are the outer electron shells always filled first?
No. The inner shells are filled first.
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
How many electrons are in the outer shells in fluorine?
1
What elements had complete outer shells and why?
Group 0
Why noble gasses are not active?
Noble gases are not active because of their outer shells. The outer shells of these gases are full of 8 valence electrons, which make them stable and inert.
How many outer shells are around the nucleus of darmstadtium?
Darmstadtium has seven electron shells around the nucleus.
Hard outer shells which are sometimes made into bottles?
gourds
What is the outer energy level of californium?
Californium has seven electron shells ; the outer shell has two electrons.
