What else can I help you with?
Which number tells you the number of valence electrons?
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
The group number on the periodic table corresponds to which characteristic of the elements of that group?
use your brain.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
How many valence electrons do the nitrogen family have?
The nitrogen family comprises of the group 15 elements which consist of nitrogen, phosphorous, arsenic, antimony and bismuth. All these elements have five valence electrons.
Do each of the elements in Group 1 have the same or different numbers of electrons?
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
Which number tells you the number of valence electrons?
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
The group number on the periodic table corresponds to which characteristic of the elements of that group?
use your brain.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Which has a different number of valence electrons oxygencarbonsulfurselenium?
Carbon is in group 14 and has 4 valence electrons, oxygen sulfur and selenium are in group 16 and have 6 .
What is the valence number for helium?
He has 2 valence electrons. Look on a periodic table. It will show He only has 2 protons and the number of protons and electrons is equal. It is an exception to the rule of group numbers corresponding to valence numbers.
What property of an element does the group number identify in a numbering system that uses a and b?
The number of valence electrons. :) have a good day breh

The nitrogen family comprises of the group 15 elements which consist of nitrogen, phosphorous, arsenic, antimony and bismuth. All these elements have five valence electrons.
What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
How does the periodic table indicate the numbers of valence electrons an element has?
The group number of an element on the periodic table corresponds to the number of valence electrons it has. For main group elements (groups 1, 2, 13-18), the ones digit of the group number gives the number of valence electrons. For transition metals and inner transition metals, the number of valence electrons can vary.
