Question

name: maquzstay mod: 3b date: acb2: getting to know the periodic table assignment (icp - mihay) go to the following website: https://ptable.com/?lang=en#properties (or search for \ptable\) 1. the up and down columns on the periodic table are called: 2. the side to side rows on the periodic table are called: 3. using your mouse, slide the arrow back and forth between the metals and nonmetals boxes (top middle above the periodic table). notice that as you do this, some boxes go white and others are highlighted with color. a. when you hover over the metal box, which side of the periodic table is highlighted in color (left or right)? b. when you hover over the nonmetal box, which side of the periodic table is highlighted? c. when hovering over the nonmetal box. you will find one element that is highlighted green that is not on the nonmetal side of the periodic table. what element is it? 4. hover over the following boxes. write the group number(s) for each of the following. the group numbers are across the top 1 - 18: name: group number alkali metals alkaline earth metals transition metals post transition metals reactive nonmetals noble gases 5. locate the lanthanoids and actinoids find the blue box left of the lanthanoids and actinoids. it is a tall rectangle with the numbers 6 and 7 in it. above the 6 and 7 there are the numbers 57 - 71 and 89 - 103. a. what happens when you click on that box? b. what 2 periods are the lanthanoids & actinoids in? c. what groups are the lanthanoids & actinoids in between? d. why do you think the lanthanoids and actinoids are written below the periodic table? (to undo the wide version of the periodic table, go to the top and click on the \wide\ tab). 6. states of elements are room temperature. hover over the solid, liquid, or gas square to find the answers. a. most elements are ____________ at room temperature. b. how many elements are a gas at room temperature? c. how many elements are liquids at room temperature?

Explanation:

1. The up - down columns on the periodic table are groups or families.
2. The side - to - side rows are periods.
3. a. Metals are on the left side of the periodic table, so when hovering over the metal box, the left side is highlighted.

b. Non - metals are on the right side, so the right side is highlighted when hovering over the non - metal box.
c. Hydrogen is often considered a non - metal but is sometimes highlighted in a way that may seem out of place among non - metals on the table.

1. Alkali Metals: Group 1; Alkaline Earth Metals: Group 2; Transition Metals: Groups 3 - 12; Post - Transition Metals: Groups 13 - 16 (in part); Reactive Nonmetals: Groups 15 - 17; Noble Gases: Group 18.
2. a. Clicking on the box may expand or provide more information about the Lanthanoids and Actinoids.

b. Lanthanoids are in period 6 and Actinoids are in period 7.
c. They are in between groups 3 and 4.
d. They are written below to keep the periodic table more compact and to show their unique electron - configuration and chemical properties.

1. a. Most elements are solids at room temperature.

b. There are 11 elements that are gases at room temperature.
c. There are 2 elements (mercury and bromine) that are liquids at room temperature.

1. Groups or Families
2. Periods
3. a. Left

b. Right
c. Hydrogen

1. Alkali Metals: Group 1

Alkaline Earth Metals: Group 2
Transition Metals: Groups 3 - 12
Post - Transition Metals: Groups 13 - 16 (in part)

Noble Gases: Group 18

1. a. May expand or provide more information about Lanthanoids and Actinoids

b. Period 6 and Period 7
c. Between groups 3 and 4
d. To keep the periodic table more compact and show their unique properties
