Rb how many protons and electrons




















Name Rubidium Atomic Mass How much is 1g of rubidium? How many neutrons does nitrogen have? How many neutrons does magnesium have?

What element has 16 protons and 18 neutrons? Is rubidium a metal or nonmetal? What element contains 34 protons? What element has 4 neutrons and is a metal? Why is rubidium dangerous? How do you find the electrons? What is SR on the periodic table? What reacts with rubidium? How many rings does cesium have? Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force , while protons repel each other via the electric force due to their positive charge.

These two forces compete, leading to various stability of nuclei. There are only certain combinations of neutrons and protons, which forms stable nuclei. Neutrons stabilize the nucleus , because they attract each other and protons , which helps offset the electrical repulsion between protons. As a result, as the number of protons increases, an increasing ratio of neutrons to protons is needed to form a stable nucleus. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoes radioactive decay.

Unstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. Many other rare types of decay, such as spontaneous fission or neutron emission are known.

It should be noted that all of these decay pathways may be accompanied by the subsequent emission of gamma radiation. Pure alpha or beta decays are very rare. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule or other physical structure in atomic or molecular orbitals.

Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state.

The low toxicity of rubidium is confirmed by a study from which aimed to assess the feasibility of using rubidium chloride as an anti-depressant, since similar effects had been observed in monkeys.

After being given 23 grams of rubidium over 75 days, a volunteer showed no harmful side effects. It does though make you wonder whether equivalent clinical studies could take place now. Meanwhile, clinical applications of rubidium in psychiatry have yet to come to fruition. So there we have rubidium, the explosive red element number 37 in the periodic table. So this explosive element may have minimal commercial applications but can be used in atomic clocks and has isotopes that can locate brain tumours.

Not bad considering it was stumbled upon when analysing the mineral lepidolite. That was Tom Bond with the story of rubidium. Now next week we meet the element that's made our modern lifestyles possible. A mixture of powdered tantalum and tantalum oxide is used in mobile phone capacitors, components that store electrical charge and control the flow of current.

What makes the element ideal for phones, and for other dinky electronic gadgets, such as handheld game consoles, laptops and digital cameras, is that the metal is extremely good at conducting both heat and electricity, meaning that it can be used in small components that don't crack up under pressure.

And John Whitfield will be explaining why we have tantalum to thank the next time we play the latest computer games, take hundreds of photos on holiday or when we're downloading this podcast on our laptops. So join John on next week's Chemistry in its Element.
