Similarly one may ask, how many protons neutrons and electrons does rubidium 87 contain?

An electron has very little mass by comparison, protons have a positive charge, electrons have a negative charge, and neutrons-none. The nucleus of 87Rb contains 37 protons(p) and 50 neutrons(n).

Beside above, what is the atomic mass of rubidium 85? Rubidium has two naturally occurring isotopes, Rubidium-85 (relative mass 84.9118 amu) and Rubidium-87 (relative mass 86.9092 amu). If rubidium has an average atomic mass of 85.47 amu, what is the abundance of each isotope (in percent, %)? Be sure to report the correct number of significant figures. 3.

Where is cesium found?

Source: Cesium is found in the minerals pollucite and lepidolite. Commercially, most cesium is produced as a byproduct of the production of lithium metal. More than two-thirds of the world's reserves of Cesium – 110,000 tonnes – are found at Bernic Lake, Manitoba, Canada.

Is rubidium found in the human body?

Rubidium is a soft, silvery-white metallic element of the alkali metal group, present in traces amounts in human tissues and fluids. It has been found slightly increased in neoplastic human breast tissues obtained from patients at the time of mastectomy, compared to normal tissue.

How many energy levels are in cesium?

Why is rubidium dangerous?

Safety. Rubidium compounds are not very dangerous in the human body; however, if a person gets too much from eating, they could get sick because it acts like other alkali metal ions such as sodium ions in sodium chloride. It reacts with air and water and makes the corrosive substance rubidium hydroxide.

What does rubidium do in the body?

Rubidium is not particularly harmful to humans, and once in the body its ions are rapidly excreted in sweat and urine. Rubidium chloride has been used to study the transport of potassium ions in humans, since rubidium ions are not naturally found in the body and when present they are treated as if they were potassium.

Which energy level is the valence level for rubidium when it has a 1+ charge?

Rubidium has one valence electron, which is located in the s-orbital of the atom's fifth energy level. Rubidium has a total of 37 electrons, illustrated in the element's electron configuration of 1s2 2s2p6 3s2p6d10 4s2p6 5s1. As there is only 1 electron in Rubidium's valence shell, Rubidium's valency is 1.

Is rubidium 87 stable?

Rubidium 87 Chloride (Rubidium-87) is a stable (non-radioactive) isotope of Rubidium.

How do you find the electrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
