The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
Well, darling, francium is a wild child with only one electron in its outermost shell. It's living life on the edge, ready to jump into any chemical reaction that comes its way. Just one electron, but oh boy, does it make a splash!
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
Francium has 87 positively charged protons and 87 negatively charged electrons, plus a varying number of uncharged neutrons, of which 136 is the commonest amount. Number of neutrons = Atomic mass of the isotope - 87
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
Francium has 87 electrons.
Francium has 87 electrons.
Francium has 87 protons and 87 electrons.
The ion Fr+ has 86 electrons.
There are 87 electrons is Francium. There are also 87 protons, 87 neutrons and, by extension, the atomic number is also 87.
Francium has only one valence electrons.
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.
Francium has 87 electrons; one is the valence electron.
Francium lose one electron to form the cation Fr+.
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
Francium is a non metal element. There are 87 electrons in a single atom.
Francium is an alkali metal that will lend electrons in an ionic compound.
