Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
How many valence electrons does an element in group 4 have are they reactive?
All elements in group four have FOUR valence electrons. This is easy to remember because the group number located at the top of the periodic table of elements corresponds precisely in all cases to the experimentally observed number of valence electrons in the elements. It is also important to know that the elements in group eight (the inert gases) all have eight valence electrons, meaning that they can neither gain or lose electrons in the way of bonding with other elements, thus the maximum number of valence electrons any molecule can have is eight.
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
What is the number of protons in the nucleus or the number the electrons in the energy levels called?
valence electrons
The ability of atoms to combine with other atoms is determined by?
The number of electrons of both atoms and its valence number.
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
How many electrons are in the highest occupied energy level of oxygen?
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
Elements in a group or family have similar properties?
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.

Which of the elements which have their valence electrons in the second energy level is the largest?
Neon
What can you predict from an elements place in th periodic table?
its valence electrons, its number of energy levels, how reactive it is, and some properties it has
Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
Why is it significant that valence electrons are located in the outermost energy level of an atom?
The valence electrons are the electrons that undergo chemical bonding in the main group or representative elements.
What is the number of protons in the nucleus or the number the electrons in the energy levels called?
valence electrons
