How many goals have been completed? How many performance goals do workers have in a given review period? Which goal plans are associated with worker's goals? How many development goal tasks does a worker have? How many goals have tasks? How many performance goal tasks does a worker ha...
Electrons fill out their shells and subshells in the same order every time, filling the shells closer to the nucleus first and then expanding out from there. The amount of electrons and the shells they fill are part of what ...
How many valence electrons do atoms of each of the following elements have? Na, Ar, Al, P How many valence electrons are in NH4+? How many valence electrons are in PF3? How many valence electrons are there in PO_3^{-3}? a. 20. b. 26. c. ...
In the periodic table, an element is defined by its vertical group and horizontal period. Each period, numbered one through seven, contains elements of increasing atomic number. Unlike Mendeleev's original list, the modern periodic table is based on atomic number, or the number of protons in a...
How many electrons can be in each orbital? Consider the electron configuration for iron. How many outer electrons does it have? How many total electrons are in a Fe2 ion? How many total electrons are in a Fe2+ ion? How many of the following elements have 2 unpaired electrons in the grou...
With Shopify POS, for example, you’ll see how many items are available in each location. As soon as items are running low, set up an alert to restock. That way, you never have to turn in-store away because you don’t have a product they want in their size or color. ...

While studying about the periodic table we always note a fact that in a group, all the elements will have the same number of valence electrons and as we move down the group new shells aer introduced.The period to which an element belongs to represents the outermost shell of the element.Sin...
Properties of an element can be predicted by using a periodic table. We can see many patterns in the physical and chemical properties of elements as we descend in a group or move across a period in the Periodic Table. The periodic trends can be explained in terms of the number of el...
