Document Summary

If you want to convert the velocity of an object from m. s to km/s what units must the conversion factor have: (km/m)(s/h) The periodic table: types of elements, metals: Ductile (pulled into a wire: all of these properties are metals, some of these properties are metalloids. Naming compounds: elements, atomic, molecular, compounds, substances made up on more than one type of element. What is an ionic compound: a compound formed from cations (+) and anions (-) held together by electrostatic forces, e. g. Ionic compounds exist as 3d network structures (+)(-) charges. Ionic compounds are generally composed if a metallic cation and a non-metallic anion (left hand side of the pt: the sum of the charges on the cation(s) and anion(s) in each formula unit must equal zero. If the first element is a metal ionic. Naming ionic compounds: ionic compounds (binary, x-y, x metal cation, y anion, name: cation name + root anion name + (cid:858)ide(cid:859, e. g.

Place the elements in their proper position on the periodic table. To make this more challenging. I have not included their identities. Instead of the usual chemical symbol, each element is represented by a code letter. Some clues to the element's identities are listed below. In addition, the elements fall into these families or groups.

JKQ, WNVG, IAL, EPFZ, YBR, ODS, CXU, THM

Place each code letter in its proper space in the table below. Indicate the actual chemical symbol that corresponds to each letter.

V is an inert gas

E is an alkali metal

U is a halogen

D is in family VA

J is an alkaline earth metal

T is in family VIA

R has one less proton than A

A has six protons in its nucleus

R has an atomic number one more than J

O has an atomic number one more than A

S has 8 more protons in its nucleus than D

F has only one proton in each atom

Y has atoms that are larger than the atoms of B

I has the largest atomic number in its group
