Into the SPDF blocks.

so groups 1 and 2 are S

Groups 3-12 are D

Groups 13-18 are P (except He, He is 2s)

and the lanthanides and actinides are F

Can properties of elements be predicted by their placement on the periodic table?

Yes. Properties of elements can be predicted by their placement on the period table.There are 5 metal groups:* Alkali Metals* Alkaline Earth Metals* Transition Metals* ActinoidsThere are 3 Nonmetal groups:*Other nonmetals*Halogens*Noble GasesAnd then there is Metalloids.Thank you for your time...Xoxo,Love,Nikki L.


Which elements have electron configurations that end in ns 2 np 5?

The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.


What is a block on the periodic table and how does it contribute to the organization of elements?

A block on the periodic table refers to a specific region where elements are grouped based on their electron configurations. These blocks help organize elements by showing patterns in their properties and behaviors. Each block represents a different type of electron arrangement, which can help predict an element's characteristics and its placement in the periodic table.


Which elements have electron configurations that end in ns 2 and np 5?

The elements with electron configurations that end in ns 2 and np 5 are found in Group 17 of the periodic table, known as the halogens. This group includes elements such as fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).


What are the examples of elements with predictable electron configurations?

All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.

Is the periodic table is most easily understood in terms of the electron configurations of the elements?

Yes, understanding the electron configurations of elements can help explain the arrangement of elements on the periodic table. Electron configurations determine an element's chemical properties, reactivity, and position within the table. The periodic table is organized based on recurring patterns in electron configurations, such as the filling of energy levels and sublevels.
