Consider
fluorine
atoms with 9 protons and 10 neutrons.
What particle has 9 protons and 10 electrons?
So,
an F – ion
has 9 protons and 10 electrons.
What element has 9 protons and 10 neutrons and 10 electrons?
| Name Fluorine | Atomic Mass 18.998 atomic mass units | Number of Protons 9 | Number of Neutrons 10 | Number of Electrons 9 |
|---|
What nuclide has has 9 protons and 10 neutrons?
By looking at the periodic table, you will see that
Fluorine
has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.
What is the mass of an element with 9 protons and 10 neutrons?
The mass number is clearly
19
.
What is the mass number of 19 9 F?
The mass of neutral 199F 9 19 F is equal to
18.998403 atomic mass units
.
What element has 18 protons and 22 neutrons?
| Name Argon | Atomic Mass 39.948 atomic mass units | Number of Protons 18 | Number of Neutrons 22 | Number of Electrons 18 |
|---|
Can you have 0 neutrons?
There is only one stable atom that does not have neutrons. It is
an isotope of the element hydrogen called protium
. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.
What is the number at the end of an isotope's name?
– The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope's name is
the -mass number
. While looking at xenon (Xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group.
Which species has 9 electrons?
The element
fluorine
has 9 protons and 9 electrons.
What charge is a neutron?
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It
has no electric charge
and a rest mass equal to 1.67493 × 10
− 27
kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
What charge is a proton?
Protons have a charge of
+1
and a mass of 1 atomic mass unit, which is approximately equal to 1.66×10
– 24
grams. The number of protons in an atom defines the identity of the element (an atom with 1 proton is hydrogen, for example, and an atom with two protons is helium).
Who discovered proton?
It is 100 years since
Ernest Rutherford
published his results proving the existence of the proton.
What has a proton number of 9?
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.
What has 12 protons and 12 neutrons?
Magnesium
, in its elemental form, has 12 protons and 12 electrons. The neutrons are a different matter. Magesium's average atomic mass is 24.305 atomic mass units, but no magnesium atom has exactly this mass.
Why do atoms have no overall charge?
Every atom has no overall charge (neutral). This is because
they contain equal numbers of positive protons and negative electrons
. These opposite charges cancel each other out making the atom neutral.
