The table lists properties of a few known elements, but the states of matter and melting points are missing. Look up the elements in this periodic table. Click an element in the table to reveal its properties. Then add the states of matter (at 20°C) and melting points you find to the table.

Answer (Melting points)
K: 63.5 °C
I: 113.7°C
Au:1064.18 °C
Ge:938.25°C
Ba: 727 °C
Ar: −189.34°C
Cl: −101.5°C
Rb: 39.30°C
Ag: 961.78°C
Ca: 842°C
Si: 1414°C
Xe:−111.75°C

Part two: Screenshot #2
This table resembles a condensed version of the modern periodic table. Using the full periodic table as a reference, type the symbols for the elements from part A into this table based on their appropriate group and period.

Part 3: I honestly don't know fam-
(Need help on it)

Here are six unknown elements and some of their properties. Study the properties, and then answer the question that follows.
Look back at parts A and B to compare the properties of the unknown elements with the properties of the known elements. Based on these properties, match each unknown element to its group in the periodic table.

Drag each tile to the correct box.

Respuesta :

the characteristics of the periodic table we can find the answer to identify and classify  the chemical elements

The periodic table is a way of ordering the chemical elements by their atomic number, it is made up of rows called periods and columns called groups.

The rows start in an element with one electron in its last shell and end in an element with 8 electrons in the last shell.

The column all elements have the same number of electrons in the same shell.

Let's answer each part separately

First part

Find the melting point and the state of matter

Element             melting point (ºC)       state of matter

Potassium (K)           63.7                          gaseous

Iodine (I)                   111.7                           solid

Gold (Au)              1063                             solid

Germanium (Ge)    937.4                         solid

Barium (Ba)             714                            solid

Argon                    -180.4                          gas

Chlorine                -101                              gas

Rubidium (Rb)         38.9                          solid

Silver (Ag)             960.8                          solid

Calcium (Ca)         838                             solid

Silicon (Si)            1410                             solid

Xenos (Xe)            -111.9                          gas

2nd part

Write the missing elements, we use the periodic table and we place the elements by their row and column, that is, period and group.

The name and symbol of the missing elements are written in the following table

     1                       2                 11                 14            17             18

1 Hydrogen      Helium

       H               He    

2 Lithium    Beryllium                            Carbon  Fluorine     Neon

       Li                 Be                                   C               F           Ne

3 sodium    Magnesium                        Silicon       Cl               Ar

        Na                Mg                              Si

4 K                        Ca             copper     Ge       Bromine      Kripton

       K                 Ca                                 Ge         Br                 Kr

5 Rubidium  Strontium         Ag              Tin       Iodine           Xenon

      Rb           Sr                     Ag              Sn          I                    Xe

6 Cesium      Ba                    Au              Lead      Astate        Radon

       Cs         Ba                    Au                  Pb           At               Rn  

3rd part

It is requested to identify the elements by their properties.

For identification we will use the properties in the following order

  • Melting point
  • State of matter
  • Conductivity
  • Solubility in H2O

Element 1

[tex]T_m[/tex] = -157 K

matter state: gas

corresponds to the  element:    Krypton

Element 2

T_m = 777ºC

State of matter: solid

conductivity: good

Corresponds to the element: Strontium

Element 3

T_m = 327º

Solid state

Corresponds to elements: Lead

Element 4

T_m = -7ºC

Liquid state

Corresponds to Bromine

Element 5

T_m = 1085ºC

conductivity: excellent

Corresponds to the element   Copper  

Element 6

T_m = 29ºC

Solubility: reacts violently

Corresponds to the element Cesium

 

In conclusion, using the characteristics of the periodic table, we can find the answer to identify and calcify the chemical elements.
