What reacts with rubidium?

Reaction of rubidium withbasesRubidium metal reacts very rapidly withwater to form a colourless basic solution of rubidiumhydroxide (RbOH) and hydrogen gas (H₂). The resultingsolution is basic because of the dissolved hydroxide. Thereaction is very exothermic.

What is the color of rubidium?

Rubidium is a soft, silvery-white metallicelement. It is solid at room temperature but melts easily, at 39.3^oC.

How many valence electrons does RB have?

one valence electron

How are energy levels calculated?

Absorbing PhotonsThe formula defining the energy levels of aHydrogen atom are given by the equation: E =-E₀/n², where E₀ = 13.6 eV (1 eV =1.602×10^-¹⁹ Joules) and n =1,2,3… and so on. The energy is expressed as anegative number because it takes that much energy to unbind(ionize) the electron from the nucleus.

What is energy level diagram?

Chemists sometimes use an energy level diagram torepresent electrons when they're looking at chemical reactions andbonding. Chemists use the energy level diagram as well aselectron configuration notation to represent which energylevel, subshell, and orbital are occupied by electrons in anyparticular atom.

What is main energy level?

In chemistry, the principal energy level of anelectron refers to the shell or orbital in which the electron islocated relative to the atom's nucleus. This level isdenoted by the principal quantum number n. The first element in aperiod of the periodic table introduces a new principal energylevel.

Which sublevel has the highest energy?

Number of electrons per sublevel

Energy Level	Sublevels	Maximum Number of Electrons per Energy Level
1	s	2
2	s	8
2	p	8
3	s	18

What is the lowest energy level?

At the lowest energy level, the one closest tothe atomic center, there is a single 1s orbital that can hold 2electrons. At the next energy level, there are fourorbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals canhold 2 electrons, so a total of 8 electrons can be found at thislevel of energy.

What element has 4 energy levels?

Electrons

Atomic Number	Element	Energy Levels or "shells"
3	Lithium (Li)	2
4	Beryllium (Be)	2
5	Boron (B)	2
6	Carbon (C)	2

What is a discrete amount of energy called?

The state of a hydrogen atom, or any submicroscopicsystem, however, may change from one configuration to another byemitting or absorbing a discrete amount of energy. Thelowest energy level of a system is called its groundstate; higher energy levels are called excitedstates. See also Franck-Hertz experiment.

Why are energy levels quantized?

Quantized Energy StatesThe electrons in free atoms can only be found incertain discrete energy states. One of the implications ofthese quantized energy states is that only certain photonenergies are allowed when electrons jump down from higherlevels to lower levels, producing the hydrogenspectrum.

What is ground state energy?

A ground-state atom is an atom in whichthe total energy of the electrons can not be lowered bytransferring one or more electrons to different orbitals. That is,in a ground-state atom, all electrons are in thelowest possible energy levels.

What is the highest energy level of magnesium?

Magnesium has an atomic number of 12 .Theelectron configuration for Mg is 1s²2s²2p63s². Thehighest principal quantum number in magnesium'selectron configuration is n = 3, so all electrons with n = 3 arevalence electrons. Magnesium has 2 valence electrons in itshighest energy level.
