four students were asked to complete a table for a science assignment. each student selected one chemical element from each of four groups in the periodic table and then classified each element as a metal, a nonmetal, or a metalloid.

which table was completed correctly? look at image for the tables!

a) answer choice f

b) answer choice g

c) answer choice h

d) answer choice j

respond

Table which was completed correctly is :

B) Answer choice G

Explanation:

Metals : Most of the elements in the periodic comes in the category of metal. They are found in left and middle of periodic table.

List of metals

Alkali : Li , Na , K ,Rb , Cs ,Fr

Alkaline : Be , Mg , Ca , Sr ,Ba ,Ra

Transition : Sc ,Ti ,V ,Cr ,Mn , Fe , Co, Ni Cu , Zn ,Y ,Zr ,Nb ,Mo ,Tc ,Ru , Rh , Pd , Ag , Cd , In , Sn, La ,Hf ,Ta ,W ,Re ,Os ,Ir ,Pt ,Au ,Hg

Non -Metals: Most of the p-block element are non metal. They are present in upper - right corner of the periodic table.

Non - metals : H , He , C ,N , O , F ,P ,S , Cl, Ar , Br , Xe ,At ,Rn,  

Metalloid : They show properties of both the metals and the non - metals.

Also called as semimetals

Metalloid : B ,Si ,Ge ,As ,Sb ,Te ,Po

In table F :

B = metalloid  , N = non metal ( wrong-match) , Ra  = metal ( wrong-match) , He = Non - metal ( wrong-match)

In table G : Correctly matched

I =  Non - metal , Ca = metal , Rb = metal , As = metalloid

In table H:

Ni = metal ( wrong-match) , C = metalloid ( wrong-match) , Mg = metal , Pb = Metal

In table J:

Cu = metal , Sb = Metalloid( wrong-match)  , S = non metal( wrong-match) ,Ne = non metal

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

it's c (engineer's do their work with mechanical stuff not on any living being)
