Fluorine is a non metal element. Atomic Mass number of it is 19.
What else can I help you with?
Is fluorine an atom?
Fluorine is an element, not an atom. An atom is the smallest unit of an element that retains its chemical properties, while an element is a substance made up of only one type of atom. Fluorine is a chemical element with the symbol F and atomic number 9.
What is the mass in atomic mass unit of one fluorine atom?
19.0
What is the molar mass number of an element?
The unit for the atomic masses (and also for atomic weights) is the unified atomic mass unit equivalen to to 1/12 of the atomic mass of the carbon isotope carbon-12 in normal state or 1,660 538 921(73)×10−27 kg.
What element has a gram atomic mass that is greater than the gram atomic mass of the element with an atomic number higher by one unit?
Both argon and cobalt have this characteristic.
Does a element have mass in it?
Yes, an element has mass. The smallest unit of an element is the atom, and the atom's mass is the amount of matter in it: the neutron(s), proton(s), and electron(s). Because the number of protons determines an element's identity, and protons have mass, elements always have mass (though this can be a tiny, almost immeasurable mass).
What is a group of symbols that show the kind and number of each element in a single unit of a molecule called?
Mass
Is the atomic mass on the bottom or top?
At the bottom, the atomic number is at the top.
What is the atomic number of an atom with 9 protons 10 neutrons and 9 electrons?
Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass.
Average mass of one atom of an element?
The average mass of one atom of an element is given by its atomic mass, which is listed on the periodic table in atomic mass units (amu). It represents the average mass of all isotopes of that element, taking into account their relative abundance.
What is the unit of an atomic mass for aluminum?
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
When an isotope undergoes beta decay which of the following does not change A the atomic number B the name of the element C the mass number D all of these change?
B. The name of the element does not change during beta decay. The atomic number (Z) increases by one unit as a neutron is converted to a proton, while the mass number (A) remains the same.
What is the atomic mass unit of Alluminium?
Aluminium is a meta element. Atomic mass of it is 27.
