How many electrons does the isotope oxygen-18 have?
8 electrons
A neutral atom of oxygen-18 will have 8 electrons. The way to determine this is to look at the atomic number of oxygen, which is 8.
How many electrons does oxygen 17 have?
eight electrons
In one atom of the oxygen-17 isotope, there are eight protons, nine neutrons, and eight electrons.
How many neutrons are present in the nucleus of oxygen-18?
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.
How many protons neutrons and electrons are there in a neutral atom of the isotope of copper named Copper 65?
An atom of Cu-63 has 34 neutrons and an atom of Cu-65 has 36 neutrons. 27- The total number of electrons in an atom of Cu-65 is 29 because copper has atomic number of 29, which simply means that an atom of copper has 29 protons and 29 electrons.
How many electrons are in a neutral atom of 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 protons neutrons and electrons are there in a neutral atom of oxygen 18?
18O2− has 8 protons, 10 neutrons, and 10 electrons.

How many protons does a neutral atom of oxygen-16 have?
8 protons
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 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.
How do you calculate the number of electrons in a neutral isotope?
In a neutral isotope, the number of electrons equals the number of protons. Like finding the number of protons, finding the number of electrons in a neutral isotope requires finding the atomic number of the element.
How many electrons does oxygen-16 have?
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.
How many electrons does a neutral oxygen atom have?
A neutral oxygen atom (Z = 8) has eight electrons, and if it gains two electrons it will become an anion with a 2− charge (8 − 10 = 2−). Iodine is an essential trace element in our diet; it is needed to produce thyroid hormone.
What is the atomic number of an iodine atom?
The 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 is the atomic number of an isotope written?
The symbol for a specific isotope of any element is written by placing the mass number as a superscript to the left of the element symbol ( Figure 4 ). The atomic number is sometimes written as a subscript preceding the symbol, but since this number defines the element’s identity, as does its symbol, it is often omitted.
A neutral atom must contain the same number of positive and negative charges, so the number of protons equals the number of electrons. Therefore, the atomic number also indicates the number of electrons in an atom. The total number of protons and neutrons in an atom is called its mass number (A).
