In methane the total number of groups of electrons on the central atom is?

There are four pairs of electrons around the central carbon atom of methane. These pairs each consist of one electron originally from the carbon and one from the hydrogen atom bonded to it.
Though the question only considers the outer shell of electrons, as that is the only shell used for bonding, it may be useful to remember that in methane the carbon atom has a total of ten electrons around it, due to its two inner electrons.

How do you figure out how many valence electrons an atom has based on its location on the periodic table?
For groups 1-2 the number of valence electrons is equal to the number of the group.For groups 13-18 the number of valence electrons is equal to the number of the group, but with numbering starting up from 3 (13), 4 (14) , etc. (transition metals excluded).
How many electrons surround the central Xe atom?
The atomic number from a periodic table is the number of electrons each known element has in its orbit. The atomic number of Xe is 54, therefore Xenon (Xe) has 54 electrons in its orbit.
How many electrons are in the outer shell of the elements in the groups?
the number of valence electrons is directly proportional to the group number in which the element is forund in the periodic table. for example, chlorine is in Group 7 so it has 7 valence electrons.
How many electrons are present in 4g methane?
Let us get number atoms of the constituent first.4 grams CH4 (1 mole CH4/16.042 grams)(6.022 X 1023/1 mole CH4)= 1.5 X 1023 atoms of methane========================so,Carbon is one to one in the molecular formula, so let's get the number of hydrogen atoms in this mass methane.1.5 X 1023 atoms CH4 (4 mole H/1 mole CH4)= 6 X 1023 atoms hydrogen======================now, we proceed to find electrons1.5 X 1023 atoms carbon * 6 electrons= 9 X 1023 electrons carbon--------------------------------------6 X 1023 atoms hydrogen * 1 electron= 6 X 1023 electrons hydrogen--------------------------------------------added together= 1.5 X 1024 electrons in 4 grams methane-------------------------------------------------------------( call it 2 X 1024 electrons methane to be in line with significant figures )
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.

Why doesn't a methane molecule have a charge?
In methane, the combined protons from the carbon and hydrogen, are equal in number to the combined amount of electrons. This gives a total net charge of 0, it is neutral.
What on periodic table groups have in common?
The groups have equal number of valence electrons. The elements in same groups have same chemical properties.
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
How do you figure out how many electrons are in groups 13-18?
The total number of electrons in any atom is the same as the atomic number. The number of valence electrons in an atom in columns 13 - 18 is the second digit of the column number.
How do you determine valence electrons for groups 1-18?
For Groups 1 and 2 the valence number is the group number, for groups 13-18 it is the last digit of the group number so oxygen (group 16) would have 6 valence electrons. For all the other groups ( group 3-12, the transition metals ) they are variable.
What does groups in a periodic table have?
atoms in a group have the same number of valence electrons
What does number the groups mean with the perodidc table?
1,2 and 13-18 the number is how many valence electrons it has.
Groups or families contain elements that have properties?
All groups have the same number of valence electrons and hence have similar properties.
What can you use to ditermine the number of valence electrons of an element in the s block and p block?
For the group 1 and 2 elements, the group number is the number of valence electrons. For groups 13 - 18, subtract 10 from the group number to get the number of valence electrons.
How do you figure out how many valence electrons an atom has based on its location on the periodic table?

What do groups go by on the periodic table?
elements in a group have the same number of valence electrons.
