What else can I help you with?
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
How many electron shells does period 1 have?
Period 1 of the periodic table has only one electron shell. This shell can hold a maximum of two electrons, which are found in the hydrogen and helium atoms. Therefore, elements in this period have their electrons in the first and only shell, representing the simplest atomic structure.
How many electrons do period 3 in periodic table have?
period 3 elements in the periodic table have 3 electrons in there outher shell hence the name.
What does the period number tell about the energy leaves occupied by electrons in an atom?
The period number of an element in the periodic table indicates the highest principal energy level that electrons occupy in an atom. For example, elements in Period 1 have electrons in the first energy level, while those in Period 2 have electrons in the first and second energy levels. Thus, the period number directly reflects the number of electron shells or energy levels present in the atom. Each subsequent period adds an additional energy level.

How many electons do the elements of the most stable group have in their outer energy level?
Eight, except for helium, which needs only two because: it has only s electrons' each period or atomic shell number can include only two s electrons; and the first period can have no p, d, or f electrons.
How many electrons live in the first orbital?
2 electrons.

How many inner shell electrons does chlorine contain?
Cl is in the 17 group. It is in the 3rd period. It has 3 energy levels.
How many electrons will the first shell hold?
there are two electrons the first shell hold
What level is filled by krypton?
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
How many electrons at the maximum can be present in the first shell?
Two electrons can fit in the first shell
How many electrons can be in the first energy levels?
Two electrons can be housed in the first energy level.
