How many neutrons are in an atom of 127i?
SolutionThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).
How many protons neutrons and electrons are there in 127i -?
Main Isotopes of Iodine Iodine-127 is composed of 53 protons, 74 neutrons, and 53 electrons.

How many neutrons does oxygen have?
8 neutrons
An oxygen atom has 8 positive protons and 8 neutrons in its nucleus, and 8 negative electrons speeding around the nucleus.
How many protons electron and neutrons respectively does oxygen 16 have?
16O2− has 8 protons, 8 neutrons, and 10 electrons.
What has 15 protons and electrons and 16 neutrons?
Explanation: if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
How many neutrons and electrons are in 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.
How many protons and electrons are in oxygen?
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
How many neutrons are in oxygen?
How many electrons does oxygen 16 have?
8 electrons
The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons. You will find that the atomic weight of oxygen is about 16.
What element has 16 protons and 18 neutrons?
A quick look in the periodic table will reveal that you’re dealing with an atom of sulfur, S .
What is proton and electron of oxygen?
Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons.
How many electrons does oxygen have?
