Ionization is a process in which an electron present in the outermost orbital of an atom gets knocked out by absorbing an appropriate amount of energy. Release of electron from a neutral atom results in the formation of a cation- a positively charged ion.
Rubidium (Rb) is an alkali metal with a valence electron configuration of 5s¹. Ionization results in the loss of this '5s' electron forming a Rb+ ion. The reaction can be expressed as:
Rb (5s¹) → Rb⁺ (5s⁰) + e⁻
It’s A because +1500 kJ is before the arrow. it’s in the reactant side. so it is endothermic.
Answer: Kinetic energy is energy that is associated with the constant movement of atoms or molecules. Kinetic energy is also called thermal energy, it is a form of motion. It is the motion of waves, electrons, atoms, molecules, substances, and objects!
Hope this helps a little bit
Answer:
John Dalton
Explanation:
John Dalton (1766-1844) is the scientist credited for proposing the atomic theory. This theory explains several concepts that are relevant in the observable world.
all i know is that the formula for triangles is base times hight divided by two, so add in a number to replace the missing number, multiply it by 55 and divide the answer by two. hope this helps and i really hope you get it right! or that im right...
