What is the proton electron and neutron of oxygen?
Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles. Each kind of atom has a different number of the three particles. Protons and neutrons are in the center, or nucleus, of the atom.
What is the number of protons neutrons and electrons in oxygen 16?
Oxygen-16 is composed of 8 protons, 8 neutrons, and 8 electrons.
What period is oxygen in and why?
Positioned at group 16 and period 2 in the periodic table, oxygen is an unusually reactive non-metallic atom that forms compounds with nearly all other elements.
How do you find the period number of oxygen?
Solution : From the electronic configuration of oxygen (O = 8 = 2, 6), we find that there are six electrons in its outermost shell (second shell). Since oxygen is a nonmetal, its group number = 6 + 10 = 16. Thus, oxygen belongs to group 16 and period 2.
What is the proton of oxygen?
8Oxygen / Atomic number
What element is in group 16 Period 6?
polonium
This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po)….Atomic and physical.
| Z | Element | No. of electrons/shell |
|---|---|---|
| 8 | Oxygen | 2, 6 |
| 16 | Sulfur | 2, 8, 6 |
| 34 | Selenium | 2, 8, 18, 6 |
| 52 | Tellurium | 2, 8, 18, 18, 6 |
How many protons neutrons and electrons are there in an atom of O 17?
oxygen-17 has 8 protons and electrons. # neutrons = mass # – #protons. So, in oxygen-17, # neutrons = 17 – 8 or 9. Oxygen-17 has 8 protons, 8 electrons, and 9 neutrons.
How many neutrons are in oxygen 16?
8 neutrons
Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and 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.
Where is period 2 on the periodic table?
Period 2 elements in the periodic table include the eight chemical elements from atomic number 3 to 10: lithium (Li), beryllium (Be), boron (B), carbon (C), nitrogen (N), oxygen (O), fluorine (F), and neon (Ne). These elements are in the second row of the periodic table.
How do you find the period number?
If you are given with the atomic number of an element you can find it’s period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.
How do you find the period and group of oxygen?
Since oxygen is a nonmetal, its group number = 6 + 10 = 16. Thus, oxygen belongs to group 16 and period 2.
What is the neutron of oxygen?
The oxygen atom has therefore 8 neutrons, 8 protons and 8 electrons.
How many neutrons are in o2?
Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u….Oxygen-16.

Which element is in group 16 Period 2?
Group 16 Elements Of Modern Periodic Table

| 2 | Oxygen | 8 |
| 3 | Sulphur | 16 |
| 4 | Selenium | 34 |
| 5 | Tellurium | 52 |
What element is in group 16 period 5?
Answer and Explanation: Group 16 elements are chalcogens in which the element placed in the fifth period is -Tellurium.
How many neutrons are in O 17?
9 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.
How many neutrons are in oxygen-18?
10 neutrons
Why is oxygen in period 2?
Period 2 elements (carbon, nitrogen, oxygen, fluorine and neon) obey the octet rule in that they need eight electrons to complete their valence shell (lithium and beryllium obey duet rule, boron is electron deficient.), where at most eight electrons can be accommodated: two in the 2s orbital and six in the 2p subshell.
How many protons neutrons and electrons are in oxygen 18?
Oxygen-18 is composed of 8 protons, 10 neutrons, and 8 electrons. Oxygen-15, which is an unstable isotope of oxygen, is composed of 8 protons, 7 neutrons, and 8 electrons. It is frequently used in positron emission tomography, or PET imaging.
What is the electron configuration of oxygen?
Electron configuration of Oxygen is [He] 2s2 2p4. Possible oxidation states are -2. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.
How many electrons do two oxygens share at once?
If two oxygens get together, they have 16 electrons total. By “sharing” 4 of them, they each get to “keep” half of the remaining electrons (16 total – 4 shared = 12 remaining, 12/2 = 6 each). On each oxygen, 2 of these 6 go in the inner shell, and the other 4 go in the outer shell.
How do you calculate the number of neutrons in oxygen?
You will find that the atomic weight of oxygen is about 16. Since the weight of the protons and neutrons is about 1 (the electrons weigh almost nothing compared to protons and neutrons) and we know we have 8 protons in the nucleus, we can calculate the number of neutrons by subtracting 8 from 16 (16 – 8) which equals 8.
