What is the most stable monatomic ion formed from lithium?

The ion formed by lithium element is

Explanation:

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form ions.

Lithium is the 3rd element of the periodic table having 3 electrons.

The electronic configuration of lithium element =

This element will loose 1 electron to attain stable electronic configuration and will lead to the formation of ion.

Hence, the ion formed by lithium element is

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
