Which that the adhering to sets of facets have similar physical and chemical properties? a. Oxygen, nitrogen, carbon, boron b. Strontium, magnesium, calcium, beryllium c. Nitrogen, neon, nickel, niobium
elements deserve to be sorted into noble gases, representative elements, transition metals, or inner shift metals based upon their electron configurations
Both elements, salt (Na) and potassium (K) lied in the group 1 pillar of the periodic Table, which consists of the members the the Alkali metals family. Members in ~ a family, or column, of aspects tend come have similar chemical properties.
You are watching: How did chemists begin the process of organizing elements
Based top top the following electron configurations, recognize each facet as a representative element, transition metal, or noble gas. A. 1s22s22p63s23p63d104s24p6 b. 1s22s22p63s23p63d64s2 c. 1s22s22p63s23p2
a. This is a noble gas. It has a np6 configuration, and also 8 electron (4s2, 4p6) in its external shell. This is krypton. B. Transition element. This is iron. C. Silicon. Representative element or metalloid
atomic size increases from peak to bottom within a group and decreases indigenous left come right throughout a period
Some atoms are more stable once they obtain or shed an electron (or probably two) and kind ions. This results in a full outermost electron shell and makes them energetically an ext stable. Now, since the variety of electrons does not equal the number of protons, each ion has actually a network charge.
First ionization energy tends to decrease from peak to bottom within a group and also increase native left to right throughout a period
-cations are constantly smaller than the atoms from i m sorry the form.-anions are always larger 보다 the atom from which castle form.

Electronegativity values decrease from height to bottom in ~ a group. -representative elements, values tend to rise from left come right across a period.
Arrange these facets in bespeak of decreasing atom size: sulfur, chlorine, aluminum, and also sodium. Go your plan demonstrate a periodic trend or a team trend?
