How many tables are in the periodic table?
The periodic table is just ONE table. There are not sub-tables. The periodic table is divided into periods (the horizontal rows of the table) and groups (the vertical columns). As you move horizontally across the table, an increase is the atomic number is seen, along with trends in acidity, bonding behavior, and reactivity. The groups are arranged to contain elements that have similar properties. For example, Group 1 is called the alkali earth metals group; all are light, highly reactive metals. Many more trends and groupings exist.
Why the elements of group 1 are is generally known as alkali metals?
Group 1 of the periodic table contains elements which are basic. They form ionic salts. Henced they are called as alkali metals. When dissolved in water they have a pH more than 7.0.
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
Properties of Alkali Metals?
•The boiling points and melting points increase inthe number of carbon atoms.•Alkynes are soluble in polar solvents such as water•Have incomplete combustion
How did reactivity change within this group?
Reactivity, unlike other periodic trends, does not increase or decrease going across a period or up and down a group. Instead, the least reactive elements are found in the center of the d block and in group eight (the noble gases). Reactivity then increases moving to the left and right ends of the table. The most reactive elements are found in the upper right hand corner of the p block and the lower left hand corner of the s block.
What are the trends in reactivity with HCl in alkaline earth metals?
The Alkali Earth metals are found in group 1 and 2 of the periodic table. When reacted with hydrochloric acid, the vigour of the reactions increases going down the groups. So Lithium will react gently with hydrochloric acid whilst Caesium will react explosively. The same applies for the group 2 metals. Generally speaking, Alkali metals will react with hydrochloric acid: X + HCl -----------> XCl + H2 Where X is the alkali metal and will react to form a chloride

What periodic trends are most significant in metals?
Metals form cations. They loose electrons.
Why the elements of group 1 are is generally known as alkali metals?
Group 1 of the periodic table contains elements which are basic. They form ionic salts. Henced they are called as alkali metals. When dissolved in water they have a pH more than 7.0.
What are the columns and rows of the periodic tables of the elements called?
A group or family is a vertical column in the periodic table. A period is a horizontal row in the Periodic Table. Some groups have specific names also; alkali metals, alkaline earth metals, halogens, pnictogens, chalcogens, and noble gases. However, some other groups, such as group 7, have no trivial names and are referred to simply by their group numbers, since they display fewer similarities and/or vertical trends.

Would you expect cesium to be more or less reactive than potassium?
AnswerDespite the fact that you could look it up that cesium is indeed more reactive than potassium, you could also take into account the periodic trends. One of these trends is that metals tend to be more reactive as you proceed down a group/family and as you move to the left of the table. Since both cesium and sodium are members of the alkali metals, cesium should be more reactive of the two.
How are the topics of ion formation and periodic trends related?
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).
What does it mean if a chemical or physical property is periodic?
The modern periodic table is based on the periodic law, which states that physical and chemical propertiesof the elements are a periodic function of their atomic numbers.Yes this answer is good!
How do periodic trends affect bonding?
Periodic trends affect bonding due to the arrangement of the elements on the periodic table. The periodic table only includes chemical elements.
What are the names of the trends in the periodic chart?
No
What did organizing information on the periodic table reveal?
Periodic patterns and trends
