What are the 3 main rules of the electron configuration?
Atoms can have as many electron shells as they need. The first electron shell can only contain 2 electrons but the rest can contain 8. Electron arrangement patterns down a group : the # of complete electrons shells increases by 1. The # of group is the same as the # of electrons in the outer shell. (ex. Group 2 there will be 2 electrons in the outer shell) Electron arrangement patterns across a period : the # of complete electron shells stays the same. The # of electrons increases by 1 each time. When a new period starts, that's when a new shell is added. Hope this was helpful :)
What is mercurys core up of?
Mercury's core is made of iron, with a diameter of 3600 km to 3800 km. The silicate outer shell is only 500 to 600 km thick. At least some of the core is molten.

Does absolute motion only exist in outer space?
There is no such thing as "absolute motion" - neither in outer space, nor anywhere else. Motion must always be specified in relationship to some other object.
What are the similarities between lipids and carbohydrates?
I haven't been able to find a lot of similarities but here are a few: ~They are both used for consumption ~Both are made of at least Carbon and Hydrogen (Lipids are made of only carbon and hydrogen and carbohydrates are made of carbon, hydrgen and oxygen)
Where can you buy paua shell?
You can buy it online. Paua ,endemic toNew Zealand, the shellfish Haliotis iris,is a traditional delicacy of the New Zealand Maori people who also prize it for its brightly-colored iridescent shell. Theyuse it forarts,crafts, and jewelry. Paua are only found below the low tide zone in extremely rocky and waveswept parts of the New Zealand coast. These very rugged conditions not only make the shellfishchallenging to collect, but also mean that the shells are rarely washed up on the shore unbroken. Intact shells are hard to come by if you do not actively collect the shellfish or know someone who does, so purchasing them can be the next option. If you wish to buy paua shell, then the best place to start is the tourist souvenir trade where the paua shell's decorative qualities have made it aNew Zealand icon. There are also many sites online makingNew Zealand paua shell available to the world at large. These paua shells usually have the coarse exterior of the shell ground off and are highly polished (it is the interior of the shell that is naturally iridescent).In New Zealand, whole shells in their natural state can often be found in junk shops and thrift stores, particularly in towns and cities in regions where paua are found. Small bags of broken shell pieces can also be purchased in craft stores and the craft section of big box department stores.Note: If buying paua shell on-line, beware of the terms 'abalone', 'sea opal' or 'sea ear'. In New Zealand these terms are not synonymous with paua.The Maori language dictates that only the three species of abalone (Haliotis iris, Haliotis australis, Haliotis virginea) called Paua are actually paua but it is only Haliotis iris that has the spectacularly coloured shell.

How many electrons does one hydrogen atom have in its outer shell?
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
How many electrons on their outer shell does hydrogen have?
Only one electron for hydrogen.
How many electrons for hydrogen does it take to fill its outer shell?
Hydrogen can hold only 1 electron.
How many electrons are needed to complete outer shell of hydrogen?
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
Why hydrogen is located in group 1?
The group number determines how many electrons are on the outer shell of the atom. Because Hydrogen only has 1 electron, it has 1 electron on it's outer shell. (Therefor classed in group 1)
How many electrons fill the outer shell in hydrogen?
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
How many electrons fill the outer shell of helium?
There is only one electron inhabiting hydrogen and the compound therefore only has one shell, effectively making that shell the outer shell. TL;DR There is 1 electron in the outer shell of hydrogen.
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
How many additional electrons does a hydrogen atom need to complete its outermost energy levels?
Hydrogen needs only 1 electron to complete its outer shell. the configuration of Hydrogen is 1s1 this indicates that it has only 1 electron in the shell S.and to complete the S shell H needs only one electron as the capacity of the S is 2.
Does lithium have a full outer shell?
no it only has 1 electron in the outer shell
Why is hydrogen placed in group one of the periodic table?
Group one metals are the Alkali Metals, but Hydrogen is placed in group one because of its electron arrangement. All group one metals have one electron in their valence shell (outer most shell) and hydrogen is no exception. It has one electron in its last shell, and is therefore placed in group one even though it is not an alkali metal.
Why doesn't a hydrogen form more then one covalent bond?
Because it needs only 1 electron to complete it's outer electron shell.
