What are the similarities between group 1 and group 2 elements?
These elements are highly reactive and the reactivity of these metals increases as you go down the group. These elements also react vigorously with water. Both Group one and two metals have similar patterns.
What are group 1 and group 2 elements known as?
Group names
| New IUPAC name | Old IUPAC (Europe) | IUPAC recommended trivial name |
|---|---|---|
| Group 1 | IA | hydrogen and alkali metals* |
| Group 2 | IIA | alkaline earth metals* |
| Group 3 | IIIA | |
| Group 4 | IVA |
What do all group 2 elements have in common 1 point?
The property that is common to all group 2 elements is that they tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.
What does group 1 have in common?
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 is the difference between group 1 and group 2 exam?
Group 1 are the honor (high position) jobs through the SSC where as Group 2 are the clerical or the junior positions. The two groups are administered by the SSC and is mainly for the state government level recruitment, hence may differ in the eligibility, requirements and procedure.
What is Group 7 also called?
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’.
Is group 1 metals soft?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are also relatively soft metals: sodium and potassium can be cut with a butter knife.
What is the largest element in group 1?
Key Concepts
| Trends: Decreasing | Group 1 Elements | |
|---|---|---|
| Melting Point | First Ionisation Energy | name |
| highest | largest | lithium |
| ↑ | ↑ | sodium |
| ↑ | ↑ | potassium |
Is Group 2 reactive?
Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals. All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.
What do all Group 2 elements have in common?
All the group 2 elements have 2 valence electrons (or 2 electrons in outermost orbit). Plus, these group 2 elements also show similar physical and chemical properties. Thus all the elements of group 2 have same number of valence electrons (i.e 2) and also they have common properties.
What are the members of the Group 1 element?
The members of this group 1 are as follows: 1 Hydrogen (H) 2 Lithium (Li) 3 Sodium (Na) 4 Potassium (K) 5 Rhubidium (Rh) 6 Caesium (Cs) 7 Francium (Fr)
How are Group 7 elements similar to each other?
Similarly, the atoms of all group 7 elements have similar chemical properties and reactions to each other, because they all have seven electrons in their outer shell. previous 1
Are there any alkali metals in Group 2?
Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals. All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.
