Elements in group 15 (or group 5) are non-metals. Thus, elements in group 1 lose electrons, forming positively charged cations, which are gained by elements in group 5, forming negatively charged anions. The attraction between anions and cations is known as an ionic bond.
Example, the reaction between sodium and nitrogen:
2 Na(s) + 3 N2(g) --> 2 Na3N(s)
The formula is due to sodium having a valency of 1 and nitrogen having a valency of 3. These 'cross over' producing the symbolic formula Na3N.
Elements in group 1 (alkali metals) react with elements in group 15 (pnictogens) to form ionic compounds through transfer of electrons. Alkali metals lose an electron to form a +1 ion, while pnictogens gain three electrons to form a -3 ion. Examples include the formation of compounds like Na3N (sodium nitride) or K3P (potassium phosphide).

What group of elements react by losing one electron?
The alkali metals in group 1 react by losing one electron.
What is produced when group 1 elements react with nonmetal elements?
When group 1 elements (such as lithium, sodium, potassium) react with nonmetal elements, they typically form ionic compounds. These compounds consist of a metal cation from the group 1 element and a nonmetal anion, resulting in salts like lithium chloride (LiCl), sodium fluoride (NaF), or potassium iodide (KI).
Are elements in group 1 on the periodic table?
No. The elements in group 1 (the alkali metals) are very soft, easily cut with a knife, and are highly reactive and react violently with water and oxygen. They are anything but strong, hard and corrosion-resistant.
Which groups of elements are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
What do atoms of elements in the same group of periodic table have in common?
The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
What group of elements react by losing one electron?
The alkali metals in group 1 react by losing one electron.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and Group 2 elements are highly reactive and easily lose electrons to form stable compounds with other elements. This reactivity makes them unlikely to exist freely in nature. They quickly react with other elements to achieve a stable electron configuration.
Which group of elements reacts violent with elements in group 1?
Group 17 elements, also known as halogens, react violently with group 1 elements because halogens have a strong tendency to gain electrons and form halide ions, which can displace group 1 elements from their compounds in a highly exothermic reaction. This reaction produces a burst of energy and can be explosive in nature.
Is oxygen given off when group 1 elements react with water?
No, oxygen is not given off when group 1 elements react with water. Instead, these reactions typically result in the formation of hydroxide ions and hydrogen gas.
Why the elements of Group 1 are generally known as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Which group on the Periodic Table of the Elements contains elements that react with oxygen to form compounds with the general formula X2O?
Group 16 on the Periodic Table, also known as the chalcogens, contains elements that react with oxygen to form compounds with the general formula X2O. The elements in this group include oxygen, sulfur, selenium, tellurium, and polonium.
What is produced when group 1 elements react with nonmetal elements?
When group 1 elements (such as lithium, sodium, potassium) react with nonmetal elements, they typically form ionic compounds. These compounds consist of a metal cation from the group 1 element and a nonmetal anion, resulting in salts like lithium chloride (LiCl), sodium fluoride (NaF), or potassium iodide (KI).
Which elements are most likely to react with other elements?
Elements in the alkali metal and halogen groups are most likely to react with other elements due to their high reactivity. Alkali metals like sodium and potassium readily react with water, while halogens like fluorine and chlorine are highly reactive and form compounds easily.
Oxidation number for first 20 elements?
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
Are elements in group 1 on the periodic table?
No. The elements in group 1 (the alkali metals) are very soft, easily cut with a knife, and are highly reactive and react violently with water and oxygen. They are anything but strong, hard and corrosion-resistant.
Which groups of elements are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
Why are group 1 metals knowns as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
