What are the categories on the periodic table?
The three broad categories of elements are metals, nonmetals, and metalloids. Most elements are metals. Nonmetals are located on the righthand side of the periodic table. Metalloids have properties of both metals and nonmetals.
What is common in Group 1 of the periodic table?
Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
What are the 7 elements in group 1?
Group 1 (Alkali Metals) The series consists of the elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
What is meant by group 1?
Group 1 ,2 ,3 ,4 or A,B,C,D. are various groups in which government servants are classified. Group 1 or A – highest rank job, highest pay scale , posts like district collector , commissioner , IT commissioner etc. fall into this group.
What are group 1 elements used for?
Uses of alkali metals Lithium is often used in batteries, and lithium oxide can help process silica. Lithium can also be used to make lubricating greases, air treatment, and aluminum production.
What are the 3 main types of categories for the periodic table?
The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
Which properties are characteristic of group 1 metals?
The alkali metals have the high thermal and electrical conductivity, lustre, ductility, and malleability that are characteristic of metals. Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells.
What is the family name for the group 1 elements?
Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium.
What are the group 1 properties?
The elements in group 1 are called the alkali metals . The alkali metals share similar physical properties ….Group 1 – physical properties
- are soft (they can be cut with a knife)
- have relatively low melting points.
- have low densities.
What are elements in group 2 called?
The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
What are the subjects in Group 1?
History and Culture – 30 marks. Constitution, Social Justice and International Relations – 30 marks. Indian Economy and Andhra Pradesh Economy and Planning – 30 marks. Geography – 30 marks.
What are the trends of Group 1?
Explaining the trend The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.
Why are Group I elements called alkali metals?
The elements of group 1 are called alkali metals because their oxides and hydroxides form alkaline solutions on treating with water. Therefore, the solution becomes basic or alkaline due to the formation of hyroxide ions.
What element in group 1 is not a metal but a nonmetal?
Hydrogen
Hydrogen is the only non-metal present in Group 1 of the Modern Periodic Table. The vertical columns in periodic table is called a group and horizontal row is called period.
What is group 0 on the periodic table called?
the noble gases
The elements in group 0 are called the noble gases . They exist as single atoms .
What do all Group 1 elements have in common?
Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties . When a group 1 element takes part in a reaction, its atoms each lose one electron. This forms positively charged ions .
What families are in Group One periodic table?
Periodic Table Groups and Families . Group 1 (red) Alkali metals. The alkali metals make up group 1 of the table, Li through Fr. They have very similar behavior and characteristics. Hydrogen is group 1 but exhibits few characteristics of a metal and is often categorized with the nonmetals.
What is the name of Group 1 on the periodic table?
Group 1 – the alkali metals The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.
What is Group 1 of the periodical table?
Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. Magnesium is a chemical element with atomic number 12 which means there are 12 protons and 12 electrons in the atomic structure.
What characteristics does Group 1 on the periodic table share?
The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group. Group 1 contains elements placed in a vertical column on the far left of the periodic table.
