Why group 17 elements are strong non metals while group 1 elements are strong metals?
All elements tend to react with other elements so as to attain a noble gas electronic configuration in their ions, because such a configuration usually has the lowest energy for a particular atom or ion, other factors being equal. The drive to form such an ion is strongest when the electron configuration of an elemental atom differs from the closest noble gas configuration by only one electron, and this criterion is true for both group and group 17 elements: Group 1 elements can attain a noble gas electron configuration by donating one electron to another atom, and Group 17 elements can attain a noble gas configuration by accepting one electron, thereby filling their valence shell.

Why group 17 elements are strong non metals while grour 1 elements are strong metals?
Group 17 elements (halogens) are strong non-metals because they have high electronegativity and tend to gain electrons to achieve a stable electron configuration. Group 1 elements (alkali metals) are strong metals because they have low electronegativity and tend to lose electrons to achieve a stable electron configuration.
Are Group 3A elements the alkaline earth metals?
No, Group 3A elements are not alkaline earth metals. Group 3A elements include boron, aluminium, gallium, indium, and thallium. Alkaline earth metals are found in Group 2A of the periodic table, such as calcium and magnesium.
What is the difference between alkali metal and group 2 metals?
Alkali metals belong to Group 1 of the periodic table and include elements like lithium, sodium, and potassium. Group 2 metals are known as alkaline earth metals and include elements like magnesium and calcium. The main difference is that alkali metals are more reactive than Group 2 metals because they have one valence electron, while Group 2 metals have two valence electrons.
How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
What are the elements in group IIIA called?
The elements in group IIIA of the periodic table are called the boron group. This group includes the elements boron, aluminum, gallium, indium, and thallium. They have three valence electrons and show both metal and non-metal properties.

What type of bonding do group 7 elements form with metals?
Group 7 elements, also known as the halogens, typically form ionic bonds with metals when they react. Halogens have a strong tendency to gain an electron to achieve a stable electron configuration, while metals tend to lose electrons to achieve the same stability. This transfer of electrons results in the formation of ionic compounds between the halogens and metals.
Differences between alkil metals and halogens?
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
Is strontium and alkali?
Strontium is not an alkali metal; it is an alkaline earth metal. Alkali metals are Group 1 elements, such as lithium, sodium, and potassium, while alkaline earth metals are Group 2 elements, including strontium.
What is the difference between alkali metal and group 2 metals?
Alkali metals belong to Group 1 of the periodic table and include elements like lithium, sodium, and potassium. Group 2 metals are known as alkaline earth metals and include elements like magnesium and calcium. The main difference is that alkali metals are more reactive than Group 2 metals because they have one valence electron, while Group 2 metals have two valence electrons.

What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Hydrogen is placed at the top of what column of elements?
It occurs at the top of the metals (alkaline metals) - the first group of elements but while normally shown at the top of the Group 1 elements in the periodic table, the term "alkaline metal" refers only to Group 1 elements from lithium onwards. (Lithium is the next one down)
Can group 6 and group 7 elements can only from covalent bonds?
Group 6 and Group 7 elements can form covalent bonds, but they are not limited to just that type of bonding. Group 6 elements (chalcogens) can form ionic bonds, especially with metals, while Group 7 elements (halogens) can also form ionic bonds when they react with alkali and alkaline earth metals. Thus, while covalent bonding is common among these groups, they are versatile and can participate in various types of bonding depending on the elements involved.
How group 3A-7A differ from other group A elements?
Group 2A elements form compounds that are less soluble in water. Group 2A elements are harder. Group 2A elements have an additional valence electron. Group 2A elements are less reactive.
