Group 1 elements (alkali metals) show electro positive character because they have one electron in their outermost shell, which they readily lose to form a +1 cation. This loss of electron results in a stable electronic configuration similar to that of noble gases, making them highly reactive and eager to donate electrons to achieve a full outer shell.
What else can I help you with?
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.
When elements in Group 1 lose one electron to form ions with a (an) charge.?
positive charge.
Can you explain the concept of a character table and how it is used in the study of group theory?
A character table is a tool used in group theory to analyze the behavior of group elements under different representations. It displays the characters of irreducible representations of a group, which are like "signatures" that describe how elements of the group transform under that representation. By examining the character table, mathematicians can understand the structure and properties of the group, helping to solve problems and make predictions in various mathematical contexts.
Which group of the periodic table has the elements with lowest first ionization energies?
The group with the elements that have the lowest first ionization energies is Group 1, also known as the alkali metals. This group includes elements such as lithium, sodium, and potassium, which have one valence electron that is easily removed to form a positive ion.
Why is hydrogen separate from the rest of 1A?
Hydrogen is separate from the rest of Group 1A elements because it displays unique properties that do not fit the typical characteristics of alkali metals (Group 1A elements). For example, hydrogen can form both positive and negative ions, while other Group 1A elements typically form only positive ions. Additionally, hydrogen can exhibit nonmetallic properties in addition to metal-like behavior, setting it apart from the rest of Group 1A.
What is the similarity and the difference between the two elements found in the same group?
As we move down the group ,the electrons in the valence shell remains constant but the number of shells increases by one.size of the element increases down the group .elements are more electro-positive as we move down the group so elements at the bottom are more electro-positive than those at the top.as the size of the elements increases the nuclear charge on the elements decreases.due to less nuclear charge shielding effect decreases down the group.
What Alkali metals?
Any of a group of soft, white, low-density, low-melting, highly reactive metallic elements, including lithium, sodium, potassium, rubidium, cesium, and francium. The IST Agp:is also electro positive, reducing agent and poor electro negative.
What is the low electro positive element in 5th group in periodic table?
Vinidium (V) atomic number 23 is the lowest electropositive element in this group.
What groups are most likely to react with each other periodic table?
It is about the halogens. They are in the 17th group.
In group 2 on the periodic table are they positive ions when they bond with other elements?
Elements from the group 2 of the periodic table form cations.
What are the differences between alkali metals and transition metals?
1.Both are differ in valency shell electrons 2.I-A are monovalent and II-A are divalent 3.I-A is more reactive then the II-A group . 4.I-A have more electro positive character and II-A have less electro positive character than the I-A group . 5.I-A have less ionization energy and II-A have high ionization energy than the I-A . 6.I-A have very less electro negativity than the II-A group elements. 7.I-A is soluble in water and II-A is insoluble in water . 8.I-A metals are does not react directly with nitrogen but II-A react with nitrogen directly. 9.I-A group elements are strong reducing agents than the II-A group elements. 10.The oxidation values are differ. 11.I-A obtained in solid state but II-A group in solution state 12.Decomposes on heating I-A give only oxygen but II-A group liberates both oxygen and nitrogen .

What metals are alkali metals?
Any of a group of soft, white, low-density, low-melting, highly reactive metallic elements, including lithium, sodium, potassium, rubidium, cesium, and francium. The IST Agp:is also electro positive, reducing agent and poor electro negative.
What family of elements have one positive charge?
This is the group 1 - alkali metals.
What elements of nationalism led to the revolution?
the elements are a group with a 'national' identity... a character (leader) An ideology the Will to act on that ideology
What was a logical way to group elements as more and more elements were discovered?
The logical way is to be remembered that chemical properties of elements have a periodic character.
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.
When elements in Group 1 lose one electron to form ions with a (an) charge.?
positive charge.
