What element is a metalloid with 71 neutrons?
Atomic Structure
Antimony
as 51 protons and 71 neutrons in its nucleus giving it an Atomic Number of 51 and an atomic mass of 122.
How many neutrons does fluorine have?
For example, a fluorine atom has 9 protons and
10 neutrons
. Its atomic number is 9, while its atomic mass is 19 atomic mass units.
Mercury contains 80 protons and 80 electrons and
120 neutrons
.
A French chemist
Jean-Charles-Galissard de Marignac
discovered the element named ytterbium. Erbium nitrate was heated by de Marignac until it totally decomposed, followed by extraction of the residue from which two oxides were obtained. One oxide was called erbium oxide and the other was named ytterbium.
Yttrium is often used
as an additive in alloys
. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals.
yttrium (Y), chemical element,
a rare-earth metal
of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y

.
DESCRIPTION: Thallium was discovered by Sir William Crookes in 1861. It is
a soft, heavy, inelastic metal
. Thallium is tasteless and odorless and has been used by murderers as a difficult to detect poison. It is found in trace amounts in the earth's crust.

Arsenic-75 33 protons
42 neutrons
33 electrons B.
Size of a Nucleus
This nucleus has 3 protons (which gives the nucleus a charge of +3, identifying it as the element Lithium) and
4 neutrons
(giving it a total mass number of 7). Natural Lithium is made up of two isotopes: Lithium-7 (92.5%) and Lithium-6 (7.5%).
Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have
18 neutrons in their nuclei. Other atoms of chlorine may have 20 neutrons in the nucleus
. These atoms of chlorine have different atomic mass numbers.
Cobalt has 27 protons. If the given atom has an atomic mass of 60, then it must have
33 neutrons
.
The oxygen atom has therefore
8 neutrons
, 8 protons and 8 electrons.
