Which atoms have six valence electrons in their valence shell?
The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po. If you would like to answer this yourself, just remember that the last digit of the group number is typically the number of valence electrons that you will have. The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.
What does the group number in an periodic table indicate about the structure of the atoms of all the elements in that group?
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
Atoms in the same group on the periodic table have what?
Atoms in the same group on the periodic table have similar chemical properties due to having the same number of valence electrons. This leads to them showing similar reactivity and forming similar types of compounds.
Carbon has six electrons in its valence shell True or False?
False. Carbon has four electrons in its valence shell.
What do atoms of elements in the same group of the periodic have in common?
number of valence electrons
What does groups in a periodic table have?
atoms in a group have the same number of valence electrons
How many valence electrons does a neutral atom of silicon have?
A neutral atom of silicon has 4 valence electrons. Silicon is in Group 14 of the periodic table, so it has 4 valence electrons in its outermost shell.
How many valence electron does neon atoms have?
Neon is in group 8 of the periodic table, so it has 8 valence electrons.
Which atoms have six valence electrons in their valence shell?
The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po.

The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.
How many valance electrons do atoms in group 1 group 2 and groups 15 to 17 have?
Periodic Table Group Number*: Number of Valence Electrons for Each Atom 1 : 1 2 : 2 15 : 5 16 : 6 17 : 7 ___________________ *In a wide form periodic table.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What does the group number in an periodic table indicate about the structure of the atoms of all the elements in that group?
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
Atoms that have the same number of valence electrons in their outer shell?
Such atoms belong to a group in the periodic table of elements.
How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
What is the importance of valence electrons in the organization of the periodic table?
The importance of valence electrons is that atoms in the same group ("groups" in the periodic table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D
Atoms in the same group on the periodic table have what?
Atoms in the same group on the periodic table have similar chemical properties due to having the same number of valence electrons. This leads to them showing similar reactivity and forming similar types of compounds.
