What element is in the fourth period of the periodic table with a total of 3 3d electrons?
The element in the fourth period with 3 3d electrons is titanium (element #22).
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.
How many outer shell electrons does calcium have?
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
Why does boron not always continue the Period 2 pattern of reacting electrby losing ions as do beryllium and lithium?
I know your doing your chemistry homework ..............me too do your best ............
Should you continue HCG if you get your period?
should I continue on the HCG diet if i get my period?
Why is sulfur in period 3 on the periodic table?
Sulfur is in period 3 on the periodic table because it follows the electron configuration pattern based on its atomic number. In period 3, the third energy level (or shell) is being filled with electrons, and sulfur has its electrons arranged in the third energy level.
How are the relationship of elements in a group different from the relationship of element in period?
Group - similar reacting properties. SIMILAR not identicalPeriod - ever increasing proton numberAnswer 2:elements in the same period have the same amount of energy levels (in which electrons orbit around the atomic nucleus)elements in the same group have the same number of valance electrons (which are found in the outer most energy level)
How can period number related to the location of valence electrons?
The period number corresponds to the energy level on which the valence electrons are located. As you move across a period from left to right, the number of valence electrons increases by one. This helps determine the reactivity and chemical properties of elements within the same period.
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
What does the sequence in each period represent in relation to electrons?
The sequence in each period represents in relation to electrons is that as you look from left to right on the periodic table, you see a pattern; an increase of the atomic number. The number of electrons equals the number of protons, and the number of protons equals the atomic number.
Why do element properties change in a regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
Why do properties of element change in Regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
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.
What if you get your period while the birth control patch is one?
If you get your period while wearing the birth control patch, continue using the patch as scheduled. If this becomes a problematic pattern for you, contact your health care provider.
What metallic element in period 4 has 20 electrons?
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
