Why do the elements potassium and sodium have similar chemical properties?
Because they're have the same Alkali Metals, and next to each other on the Periodic Table.
What are the elements that have the greatest reactivity located in the periodic table?
The far left - alkali metals and the far right (not noble metals but next - the Halogens.

What side of a periodic table of elements has metallic properties?
the groups of alkali metals, alkaline earth metals, transition metals, and other metal are all metals and some of the metalloids have metallic properties and the alkali, alkaline are on the left, transition metals are in the middle, other metals are located directly next to the transition metals and the metalloids are next to the other metals, and then you have halogens and Nobel gases, Lanthanides and Actinides which are all gases and rare earth.
Are alkali metals next to the alkali earth metals?
yes, the metals are next to each other
Left side of periodic table?
The right side of periodic table has non metals and noble elements. Non metals gain electrons. Noble elements are inert in nature.In the right side of the periodic table, there are the p block elements. The p block contains non metals. It has elements of solid, gas and liquid states.The rightmost elements are the noble gases, group 18. Next in the right are the non metals. Group 17 elements are also known as halogens (salt makers).
What compares alkali metals halogens and noble gases with respect to position in the periodic table the ability to react with other metals yes or non the number of electrons in the outer orbit?
Alkali metals are positioned to the far left in the periodic table. They react with hydrogen and oxygen(no they don't react with metals) and they have one electron in the outermost orbit.Halogens are positioned next to the noble gases in the periodic table. They react with nonmetals (no they don't react with metals) and they have seven electrons in the outermost orbit.Noble gases are positioned to the far to the right or last column in the periodic table. They never react with metals (no they don't react with metals) and they have 0 electron in the outermost orbit because they are very unreactive, which mean they are neutral (0/canceled).***Bold Words Important Keys for the Words***(Answers are found in page #110, 111, and 112 in the Grade 9 Nelson Science Textbook for Ontario, and also use the modern periodic table as your guide.)
Where would the element 119 be on the periodic table?
It would be the next Alkali Metal and would be placed under Francium.
What are the ways you catorgorize the elements in the periodic table?
the elements are categorised into firstly metals and non metals. metals are on the right and middle and non metals are on the left. Then they are categorised according to reactivity, for example the first column on the far left are all alkali metals, bar helium, which are highly reactive to water and air. Then the next column is of alkali earth metals, which are like alkali metals but are found more naturally are are less reactive. here's a link to a site that might help because i'm not brilliant at explaining
What are alkaline earth metals?
They are a series of elements, or metals, on the Periodic Table of Elements. The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium (i.e, the ones with two electrons in their outer shell and common oxidation state +2, right next to the alkali metals with common oxidation state +1). They're all silvery-colored and soft, and they combine with water to form alkaline hydroxides, but not as readily as the alkali metals do.
Where are the nonmetals located on the periodic table of elements?
Nonmetals are found on the right hand side of the periodic table beside noble gases.If you're looking at the periodic table of elements, imagine that there are steps with Boron (B) being on the highest step. Then on the next step below that is Silicon (Si) and so on until Astatine (At). Everything to the right of those steps are non-metals. Everything to the left are metals.
What are the elements next to the stairstep line called on the periodic table?
Elements to the left of the stair-step line are metals and to the right are the nonmetals.
