How many protons and electrons are in Rb+?

Rb atom has 37 electrons and 37 protons. when 1 electron is removed number of protons remains 37 but number of electrons is 36.36 negative charges is balanced by 36 positive charges. one extra proton is present so 1 positive charge.

How many electrons are in rubidium outermost shell?

37 electrons (white) include a relatively unstable electron in the outer shell (ring). The stability of an element’s outer (valence) electrons determines its chemical and physical properties. Rubidium is an alkali metal in group 1, period 5, and the s-block of the periodic table.

What species contains 36 neutrons?

In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4). The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass.

Which element has a total of 29 electrons?

Hence, it is the electronic configuration of copper.

What is the number of neutrons in rubidium?

Rubidium is comprised of two isotopes, one of which has a natural abundance of 72% and contains 48 neutrons in the nucleus.

What are facts about rubidium?

Rubidium is a silvery-white and very soft metal — and one of the most highly reactive elements on the periodic table. Rubidium has a density about one and a half times that of water and is solid at room temperature, although the metal will melt if it’s just a bit warmer, according to Chemicool.

What element has 1 proton and 2 neutrons?

The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (“protium”) contains just one proton, and that of hydrogen-2 (“deuterium”) contains one proton and one neutron. Naturally occurring tritium is extremely rare on Earth.
