IGCSE Chemistry - Groups of the Periodic Table

Identify the three elements indicated on the periodic table, and give the group that they are in.

Would you expect these elements to have similar or different chemical reactivity?

List several general properties of the following groups:
(a) Alkali metals
(b) Noble gases
(c) Halogens

For each of the following elements, write its chemical symbol,
determine the name of the group to which it belongs (Table
2.3), and indicate whether it is a metal, metalloid, or nonmetal:
(e) bromine.

Without looking at a periodic table, list as many noble gases as you can. (There are six common ones.)

Name at least one other element that is chemically similar to the green element.

Parts of the Periodic Table

The first atoms of seaborgium (Sg) were identified in 1974.
The longest-lived isotope of Sg has a mass number of 266.
(b) Atoms of Sg are very unstable, and it is therefore
difficult to study this element’s properties. Based on the
position of Sg in the periodic table, what element should it
most closely resemble in its chemical properties?

(b) Without looking at a periodic table, list as many alkaline earth metals as you can. (There are five common ones.)

Periodic Table: Group Names Example 1

From the following list of elements—Mg, Li, Tl, Pb, Se, Cl, Xe, Si, 
C—pick the one that best fits each description. Use each element 
only once: (a) an alkali metal, (b) an alkaline earth metal, (c) a 
noble gas, (d) a halogen, (e) a metalloidin group 14, (f) a nonmetal 
listed in group 14, (g) a metal that forms a 3+ ion, (h) a 
nonmetal that forms a 2- ion, (i) an element that is used as radiation 
shielding.

What is the group number of the green, blue, and red elements?

Classify each element as an alkali metal, alkaline earth metal,
halogen, or noble gas.
a. F

e. At

Identify the location of the element in period 4, group 6A and classify it as a metal, nonmetal, or semimetal. (LO 2.2) 
(a) Element in position a; nonmetal 
(b) Element in position b; metal 
(c) Element in position c; semimetal 
(d) Element in position d; metal

Which description of an element is incorrectly matched with its location in the periodic table? (LO 2.5–2.6) <img src="https://lightcat-files.s3.amazonaws.com/problem_images/45a49cf12234c5a3-1668117272967.jpg" alt="" />
(a) Element 3—An element in the transition metal group that is a good conductor of electricity. 
(b) Element 2—An element that is in the halogen group and does not conduct electricity.
(c) Element 4—An element in alkali metal group that is found in its pure form in nature. 
(d) Element 1—An element that is a solid at room tempera-ture, brittle, and a poor conductor of electricity.

Which of the following is a metalloid that is also a chalcogen?

Periods are horizontal rows while Groups are vertical columns on the Periodic Table.

Millikan Oil Drop Experiment

The Oil Drop Experiment helped with determining the fundamental charge of the electron.&nbsp;

Ions

Ions represent elements that possess either a positive charge or a negative charge.&nbsp;

Periodic Table: Charges

Elements lose or gain electrons to have the ideal number of outer shell electrons like the noble gases.&nbsp;

Law of Definite Proportions

"Different samples of a pure chemical compound always contain the same proportions of elements by mass."

Periodic Table: Classifications

The Periodic Table contains 3 Major Classifications when describing its elements

Isotopes

Isotopes are atoms of an element that have the same atomic number, but different mass number.&nbsp;

The Atom

The atom represents the basic functional unit in chemistry

Mole Concept

The Mole Concept involves the interconversions between different unit amounts of a substance.

Periodic Table: Representative Elements & Transition Metals

The Groups of the Periodic Table can be broken down into the Representative Elements and Transition Metals

Atomic Theory

John Dalton, one of the "Fathers of Chemistry"is credited with modernizing the Atomic Theory.

Subatomic Particles

The atom is composed of 3 subatomic particles:neutrons, protons, and electrons.

Periodic Table: Elemental Forms

The elements of the Periodic Table exist in different elemental forms in the natural world

Periodic Table: Phases

Under standard conditions of temperature and pressure, the elements can exist as solids, liquids or gases

Atomic Mass

The atomic mass of an element includes the masses of all 3 subatomic particles of neutrons, protons and electrons.&nbsp;

The Periodic Table can be further classified into Periods and Groups.&nbsp;

Law of Conservation of Mass

"In a chemical reaction, no matter is created or destroyed, but instead changes form."

Calculating Molar Mass

Molar Mass is a physical property that represents the mass of a substance divided by the amount of that substance.

Rutherford Gold Foil Experiment

The Gold Foil Experiment helped with the discovery of the positively charged nucleus.

Law of Multiple Proportions

“When 2 elements (A &amp; B) form different compounds, the mass of Element B that combine with 1 g of A are a ratio of whole numbers."

Periodic Table: Element Symbols

The Element Symbols of the Periodic Table represent the abbreviated form of an element
