Which family of elements is the most unstable and why?
Group 14, or 4A. The reason for this is in all elements there are layers of electrons, the first layer is always 2 electrons, but all the layers after that have to be 8 electrons otherwise the atom is not stable, which is why elements have charges. It is all elements goal to be stable meaning having an outer layer with 8 electrons. for example, Sodium or Na has a charge of +1 because it has 11 electrons, 2 or the first layer, 8 for the next layer leaving one electron in the last layer, +1. So it is Sodium's goal to lose one electron. With group 14 the non metals have 6 and 14 electrons. if you subtract two from these (the first layer) then divide by 8 you will come up with a number ending in .5 because they have 4 electrons in their outer layer. So they're goal is too either lose or gain 4 more electrons, in anyway that is most efficient.
Why group 16 want to bond with members of group 2?
Group 16 (oxygen family) wants to bond with members of group 2 (alkali earth metals) because group 2 elements readily donate their outermost electron to group 16 elements, forming stable ionic compounds. This electron transfer allows both groups to achieve a more stable electron configuration.
How many valence electron calcium atom has?
The first layer has two, since the maximum amount of electrons you may have in layer one are two, after the first layer you may have a maximum of eight electrons per layer, so layer one has two, layer two has eight, and layer 3 has a maximum of 18. To find the maximum number of electrons each layer can have do the equation 2(n2) n=number of layers
How many electrons on the outer most layer do bismuth have?
Five electrons in the outermost shell of Bismuth (group 15, same as 'parental' Nitrogen)
What shows the number of electrons in the outer energy level?
On the periodic table, for each element there is a column of 1 to 7 numbers on the right side, these numbers show the number of electrons in each shell, or layer, The bottom number is the number of electrons in the outermost layer
What group of elements from the periodic table is the most stable group because the outer-most layer of their electrons is full?
i dont know the answer<<<Then why did you answer??? PS: good luck with the weekly quiz bowl.

Which has 1 electron in its outside layer?
Group 1 elements have one valence electrons.

Which group of elements is the most chemically stable?
The Noble Gases Group are called 'noble' because they don't willingly react with anything. The Noble Gases are Group (or Family) 18, the column on the far right side of the periodic chart.

Do Atoms of elements in the same group have the same number of electrons in their outer layer?
Yes, atoms of elements in the same group have the same number of electrons in their outermost energy level. This outermost energy level is known as the valence shell, and it determines many of the chemical properties of an element.

What elements neutral atom has 2 energy levels with 2 electrons in the outer layer?
An element with 2 energy levels and 2 electrons in the outer layer is beryllium (Be). Beryllium has an atomic number of 4, with 2 electrons in the first energy level and 2 electrons in the second energy level, making it a neutral atom.
Why does an element gain or lose electrons to become an ion?
When elements react with other elements, they gain or loose electrons. Electrons are the reason that some elements react and others do not. Each element wants to have eight outer electrons. This is called the octet rule. (oct means eight). However, most elements do not have eight (except for the elements in the 18th column of the periodic table). The periodic table shows how many electrons each element has on its outer-layer. The last number of the column # (in the periodic table) is the number of electrons that the element contains in its outer-ring. For example, elements in the first column have one. Another way is when substances burn and reach oxygen. This is called oxidation reaction.
Why is group 17 more reactive than group 16?
The elements of this group do not have a stable number of electrons. - - - - - Group 17, the halogens, are extremely reactive (the only non-reactive elements are in group 18, the noble gases, but group 17 elements are more reactive than other group elements) because of their high "effective nuclear charge." An atom wants to have eight electrons in its outer shell, whether it's because it naturally has that many like the group 18 elements do or because it bonded to other atoms and share electrons with them. The closer to eight an atom has on its own, the higher this charge is - which makes it more reactive. Group 17 atoms all have seven electrons in their outer shells, so they are on the hunt for anything they can possibly grab. For more entertainment, the fewer shells an atom has between its "helium layer" (that lil' shell right around the nucleus with two electrons in it) and the outer shell, the higher this effective nuclear charge is. Because fluorine only has two shells, its effective nuclear charge is as high as it can get...which is why fluorine will react with anything including glass.
