Which element Is an alkali metal with a mass greater than 200?
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
What is the Alkali metal with the most massive atoms?
Bigger Atomic Number = Bigger Mass So The Answer Is Francium.
What compares atomic radius francium or cesium?
The covalent atomic radius of francium is 260 pm.The covalent atomic radius of caesium is 244 pm.
What is Francium's atomic mass?
223
What is the atomic mass for Francium?
The atomic mass of the most stable and common isotope of francium, 223Fr, is 223,019 735 9(26).
What is the atomic mass for Fr?
Francium is a non metal element. Atomic mass of it is 223.
Which has a greater atomic mass potassium or francium?
potassium
How many nuetrons does francium have?
Number of neutrons = Atomic mass of the isotope - 87
Francium's atomic number?
7 is the atomic number of francium.
How many protons and neutrons in francium?
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
How many electrons are in francium?
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.)
What is the haviest of alkaline eart metal?
87: Francium(Fr). It's atomic mass is 223.0
Which element Is an alkali metal with a mass greater than 200?
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
how does it compares atomic radius francium or cesium?
The atomic radius of caesium is practically identical to the atomic radius of francium.
Element francium has how many protons and neutrons?
Francium has 87 protons; the number of neutrons is different for each isotope and francium has approx. 40 isotopes and isomers. Number of neutrons = Atomic mass of the isotope - 87
