which is more reactive lithium or beryllium
1. which is more reactive lithium or beryllium
Lithium
Lithium is alkali metal with valency 1 and it is group 1 element due to which it can easily release its electron to form the stable cation while the beryllium is group 2 element or alkaline earth metal with a valency 2 so as it needs to lose two electrons to form the stable cation and hence it will require more energy.
This is correct answer

2. In group of potassium, sodium and lithium how does reactivity vary- increasing or decreasing from top to bottom in the periodic table?
yes because of the periodic trends. In Alkali Metals always sodiun and lithium reactivity vary in incresing and decreasing
3. Potassium,sodium,lithium are metals belonging to grouo 1. In this group how does reactivity varu increasing from top to bottom in the periodic table?
Decreasing ,because it is a metal....
4. Activity 9: Which is more reactive? Based on the trend on the reactivity of elements, identify which is more reactive on the elements below. 1.Lithium or Rubidium 2. Lithium or Helium 3. Copper or Helium 4. Nitrogen or Bismuth 5. Scandium or Vanadium 6. Tungsten or Chromium 7. Iron or Cesium 8. Manganese or Strontium 9. Indium or Aluminum 10. Gallium or Thallium
REACTIVITY OF THE ELEMENTS
The electron configuration, atomic size, and electronegativity are only a few examples of the variables that might affect an element's reactivity. The reactivity of the elements often rises as we progress down a group in the periodic table because a new energy level is added and the atomic size grows.
So, based on the locations of two elements in the periodic table, it is feasible to anticipate the relative reactivity of two elements.
For instance:
Rubidium is more reactive than lithium.Lithium is more reactive than helium.Helium is an inert gas and does not react with other elements. Copper is more reactive than helium.Nitrogen is more reactive than bismuth.Vanadium is more reactive than scandium.Chromium is more reactive than tungsten.Cesium is more reactive than iron.Strontium is more reactive than manganese.Aluminum is more reactive than indium.Gallium is more reactive than thallium.On the other hand, the reactivity of the elements often drops as we advance through a period in the periodic table due to the rise in electronegativity and the decrease in atomic size.
It is crucial to remember that reactivity might also rely on the particular circumstances and environment in which the response takes place.

19. Potassium,sodium,lithium,are metals belonging to group 1.In this group,how does reactivity vary-increasing or decreasing from the top to bottom in the periodic table?
In group 1A, the reactivity increasing from the top to bottom
Further explanationThe periodic system of elements is an arrangement of elements classified based on similar properties and their atomic number order.
The periodic system is divided into groups (vertical order) and periods (horizontal order)
The atomic number of elements in group 1A:
• H: 1
• Li: 3
• Na: 11
• K: 19
• Rb: 37
• Cs: 55
• and Fr: 87
The greater the atomic number, the more electron shells (atomic number = number of protons = number of electrons in neutral atom)
So that in group 1A, so the electron shell goes down, and the radius of the atom tends to get bigger, according to the electron shell increase. (From top to bottom)
Ionization energy is the energy that an atom needs in the gas phase to release its electrons
In one group, from top to bottom, the first ionization energy tends to get smaller, because the addition of electron shells makes the attraction of the atomic nucleus to the outer electrons (valence electron) weaker, so that it is easily released, forming cations +
Group 1A elements from top to bottom, the easier the elements release electrons, and the more reactive
For this reason, IA elements (also called alkali metal elements) are highly reactive metals (Lithium has the lowest reactivity)
