How is the element's period related to the number of energy levels over which its electrons are spread?
The period that the element's in is the same number of how many valence electrons (energy level of outer electrons) there are in the element...
What period of the Periodic Table is the element with 28 innermost electrons and 7 outermost electrons?
The group number 17 comprises of elements that has seven electrons in their own outer level.
How many electrons in the first energy level of chlorine?
Chlorine is in the 17th period.Elements in the 17th period have 7 electrons in the outermost energy level. So chlorine has 7 electrons in the 3rd energy level.Chlorine has 17 electrons. It's electron configuration is [Ne] 3s2 3p5. Therefore it has 7 electrons in its third (outermost) energy level.
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Why energy levels important in the periodic table?
The energy level tells the period in which the element belongs. Also electrons are arranged in different energy levels.
What is row on the periodic table called what do they have in common?
The row is called the period. Each element in the same period has the outermost electrons in the same shell (energy level). For example, the elements in the 3rd period all have the outermost electrons in the 3rd shell.
What element in period 3 consist of 3 electrons in its outermost shell?
aluminium

What information do the periods number give you?
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.
What do the members of a period have in common in the outermost energy level that or their valence electrons?
They are in common because the number of valence electrons stay the same
What period of the Periodic Table is the element with 28 innermost electrons and 7 outermost electrons?
The group number 17 comprises of elements that has seven electrons in their own outer level.
How many electrons in the first energy level of chlorine?
Chlorine is in the 17th period.Elements in the 17th period have 7 electrons in the outermost energy level. So chlorine has 7 electrons in the 3rd energy level.Chlorine has 17 electrons. It's electron configuration is [Ne] 3s2 3p5. Therefore it has 7 electrons in its third (outermost) energy level.
What similaries to element in the same period share?
Elements in the same grope share the same amount of energy shells, and valence electrons.
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Which transition element in the 6 period has its outermost d sublevel half-filled?
Since the d orbital can hold 10 electrons, half filled would mean it has 5 electrons. The element in period 6 that has 5 electrons in the d orbital would be Rhenium (Re).
What is the number of valence electrons (number in the outer most energy level)?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
