What element has 8 electrons and 10 neutrons?
In the case of neutrons, oxygen has different isotopes, which are different versions of oxygen that maintain their number of protons, but change their number of neutrons. In our scientific observations, oxygen has either 8, 9, or 10 neutrons.
What element has an atomic number of 8 and 10 electrons?
Answer and Explanation: An oxygen ion has 8 protons and 10 electrons. The number of protons tells us the identity of the element because the number of protons is the same as… See full answer below.
What has 8 protons and 10 neutrons?
Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
What is the octet rule 1?
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
What is the charge of an atom with 8 protons and 10 electrons?
With eight protons, we are necessarily looking at oxygen, but with 10 electrons, the net charge on the ion is minus two.
Which of the following elements has 10 neutrons?
Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside.
Which element has 8 protons 10 neutrons and 9 electrons?
The mass of fluorine is 18 u. So, fluorine has 8 protons and 10 neutrons.
Does o2 follow the octet rule?
Do the Oxygen Atoms in O2 Molecules Have Octet Configurations? Yes, each oxygen atom in the O2 molecule is surrounded by a total of 8 valence electrons. Oxygen has a total of 6 electrons in the valence shell. In order to obtain a stable octet, the two oxygen atoms share a total of four electrons via a double bond.
What is the 8 rule in chemistry?
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
What has 8 electrons 8 protons and 10 neutrons?
16O2− has 8 protons, 8 neutrons, and 10 electrons.
Does Neon have 10 neutrons?
What isotope has 10 neutrons?
Ne20
The most abundant isotope (90%) Ne20 has 10 neutrons and 10 protons.
Why does fluorine have 10 neutrons?
Therefore, the combined mass of the protons and neutrons make up the mass of the atom. The mass of one proton or one neutron has been set as one atomic mass unit. For example, a fluorine atom has 9 protons and 10 neutrons.
What is the element with 8 electrons?
OXYGEN
So… for the element of OXYGEN, you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom.
What elements does the octet rule apply?
Elements that obey octet rules are the main group elements which are oxygen, carbon, nitrogen. s-block and p-block elements obey the octet rule except for hydrogen, helium, and lithium.
Does fluorine follow the octet rule?
The fluorine atoms follow the octet rule, but boron has only six electrons. Although atoms with less than an octet may be stable, they will usually attempt to form a fourth bond to get eight electrons.
Does O2 follow the octet rule?
Each O is surrounded by four dots and two sticks or lines, representing another 4 electrons in the O2 double bond. So each O is surrounded by 8 total valence electrons, giving it an octet and making it stable.
What element has 8 protons 10 neutrons 10 electrons?
18O2− has 8 protons, 10 neutrons, and 10 electrons.
Does fluorine have 10 neutrons?
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 2 elements have 10 neutrons?
All beryllium atoms have 5 neutrons in the nucleus and all fluorine atoms have 10 neutrons.
