The last element in any period always has its outermost electron in the same type of atomic orbital, either an s or p orbital.
Any element in the group 6 and period 3 (IUPAC version of periodic table).
In 1869 when D. Mendeleev designed his periodic table any element in the period 7 was known. Today francium is in the group 1, period 7, atomic number 87.
The compound in group 7A and third period is Bromine or Br. The dot of this would be . . :Br. . . The compound in group 7A and third period is Bromine or Br. The dot of this would be . . :Br. . .
no they can bond with any other element
The number of electrons is not the key factor in determining an element, because ions can have more or fewer electrons. However, assuming an element that hasn't gained or lost any electrons, the element would be Copper.
Any counting of days regarding menstruation or fertility is always from the first day of your period - LMP is the day you started your last period, fertility window is from LMP - to days 9 thru 16 - the average cycle is 28 to 34 days beginning with LMP.
Any element in the group 6 and period 3 (IUPAC version of periodic table).
Note: When you do put a period after a URL, don't leave any space between the last character of the URL and the period.
The number of protons.
It is because it usually does not combine with any elements
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
yes periods can last any amount of days
The atomic mass of an element is equal to its molar mass in grams/mol.
the larger the highest energy level number, the larger the atomic radius
No. A rectangle is not the same as a square in any way, period.
This is sum of the atomic weights of elements contained in the formula.
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
