Could’ve reacted with water as alkali metals are very reactive to water.
Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
Answer: “ They add organic matter contributing to soil health increasing both the water-holding capacity and cation exchange capacity. They stimulate microbial activity and improve soil structure. Organic fertilizers also are valuable sources of micronutrients to plants. “ (the person above is correct)
Answer:
Valence electrons. they can be used to determine the group of an element.
