The element with 55 electrons is Caesium (Cs). Caesium is an Alkali Metal in Period 6 of the Periodic Table. It has the atomic number 55. It has 55 electrons in 6 shells with 1 electron in the outer shell.
Answer: 55 kg = 121.254 lb
55 pounds is 24,947.58 grams
55 kilos is about 8.7 stone.
Answer: 55 kg = 8.7 st OR 8 st and 9.25 pounds.
Electrons are the subatomic particles that determine the reactivity of an element. The number of electrons in the outermost shell of an atom, known as valence electrons, determines how likely an atom is to form chemical bonds with other atoms.
Cesium has 55 protons, 78 neutrons, and 55 electrons.
Cesium's atomic number is 55. Therefore it has 55 positively charged protons in its nucleus. To keep it neutral then, cesium also has 55 electrons in its electron cloud.
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
A Cesium CS ion is formed when a Cesium atom loses one electron. Therefore, a Cesium ion (Cs+) will have 55 electrons, as opposed to the neutral Cesium atom which has 56 electrons.
55
55 protons and 53 electrons would have a net charge of 2+
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
In cesium, there are 54 core electrons. This is calculated by subtracting the number of valence electrons (1) from the total number of electrons in cesium, which is 55. Core electrons are the inner electrons that are not involved in chemical bonding.
Well if I'm not mistaking, which I might be. It has 55 protons and I'm not positive on electrons but I would guess 55 also
1, as indicated by its placement in column 1 of a periodic table.
An ion with 54 electrons and a -1 charge has one more proton than the number of electrons to balance the charge. Therefore, it has 54 + 1 = 55 protons. This means the ion is an anion of an element with an atomic number of 55, which is cesium (Cs).
The ion Ce(3+) of the isotope Ce-140 has 58 protons, 82 neutrons and 55 electrons.
