Why do elements from group 1 and 7 exist mostly as compounds?
Because
Why are group 7 and group 1 elements usually found as compounds?
Group 7 elements (such as halogens) and group 1 elements (alkali metals) are highly reactive and tend to form compounds rather than exist in their pure elemental forms in nature. This is because they have a strong tendency to react with other elements to achieve a more stable electron configuration.
Why the trend in reactivity of group 7 elemnts is the opposite to the trend in group 1?
The trend in reactivity of Group 7 elements (halogens) is opposite to that of Group 1 elements (alkali metals) due to their differing electron configurations and tendencies to gain or lose electrons. Group 1 elements have one electron in their outer shell and readily lose it to achieve a stable electron configuration, making them highly reactive. In contrast, Group 7 elements have seven electrons in their outer shell and tend to gain an electron to complete their octet, which makes them more reactive as you move up the group. Therefore, while reactivity increases down Group 1, it increases up Group 7.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
How many elements are there in group 1 on the periodic table?
Group 1 on the periodic table, also known as the alkali metals group, contains 6 elements: hydrogen, lithium, sodium, potassium, rubidium, and cesium. It is located on the far left side of the periodic table.
How many elements make up group 7 group 14 and group 18?
There is a total of 17 elements in those groups.
Why do elements from group 1 and 7 exist mostly as compounds?
Because
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.

Therefore, while reactivity increases down Group 1, it increases up Group 7.
Can Group 6 and Group 7 elements only form covalent bonds?
No, Group 6 and Group 7 elements can form a variety of bonds, including covalent, ionic, and metallic bonds. The tendency to form covalent bonds increases as you move across the period from Group 1 to Group 7. Group 6 elements, such as oxygen and sulfur, commonly form covalent bonds, while Group 7 elements, such as chlorine and fluorine, tend to form ionic bonds with metals.
What trend do the oxidation numbers in group A follow?
The oxidation numbers in group A elements typically increase by one as you move from left to right across the periodic table. For example, group 1 elements usually have an oxidation state of +1, while group 7 elements typically have an oxidation state of -1.
Why group 7 element by their self do not have many uses?
This situation is normal. The number of chemical elements is smaller compared to the number of chemical compounds.
What is made when group 1 and 7 elements react together?
Did you mean group 7 or 17? Well if a group 1 and 7 element reacts it is called a Metal-Metal bond , which can be broken down into three subgroups: covalent, dative, and symmetry. If you ment Group 1 and 17 then it is an Ionic bond.
How many elements on the periodic table of elements?
In the Periodic table of Elements There are 118 Elements 96 are metals The rest are non-metals Group 7= Halogens Group 8/0= Noble gases Going down group 1 and 2, elements become more reactive
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
What is the name given to the elements in group 7?
The name given to group 7 elements in the Periodic Table are halogens.
