What s block element is not located in group 1A or group 2A in the periodic table?
hydrogen
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
Why do metals in Group 1 get more reactive nearer the bottom of the Group?
The reactivity of an element largely depends on its electronic configuration. All the 1st group elements have one electron each in the outer most s-orbital. Their reactivity is due to the loss of this electron and formation of a uni positive ion. The ease with which the element loses the electron dictates its activity. As we go down the group, the distance between the outer most orbital and nucleus increases and hence the ease with which the element loses the electron increases as we go down the group. So naturally the reactivity increases. However in the case of 7th group elements(halogens) the electronic configuration is s2p5. They acquire stability by acquiring another electron. This is called electron affinity. This increases as we go up a group. So we find the more reactive element at the top of the group. We can generalize this like this. The reactivity of an element depends on the ease with which it acquires the nearest iner gas electronic configuration.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
What are the most active metals in group 1A increases?
The reactivity of the alkali metals increases as you go down column 1 (or 1A) in a periodic table. This occurs because the first ionization energy of the metals decreases, as a result of "shielding" the outermost electrons from the attraction of the positive nucleus by the inner electrons.
What is the relationship between an alkali metal and location in group 1A and its reactivity?
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
Why is the element hydrogen not part of a group?

Which element group has the most diverse set of properties?
group 1A
What element from Group 1A is most reactive?
francium
What group has element with the most diverse set of properties?
penis
Which element has one valence electrons?
Any element in group 1
What s block element is not located in group 1A or group 2A in the periodic table?
hydrogen
Why is hydrogen placed with the element in group 1a?
valence electrons and electronic configuration.
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
In the periodic table how many group 1a atoms will need to bond to oxygen?
1a is a monovalent element and will thus need two of them to bond to oxygen to balance
Which element of the group 1A has the largest atom?
It is supposed to be francium. but since it is radioactive and less stable, cesium is generally considered to the be element with largest size.
What element is in group 1a and higher atomic number than chlorine but lower number than bromine?
Potassium
