For Argon, the number of protons is 18. This means that the number of neutrons is 40−18=22 40 − 18 = 22 . As such, the numbers of protons, neutrons, and electrons are 18, 22, and 18, respectively.
How many protons and neutrons and electrons are in an argon atom?
From the Periodic Table, we know that the atomic number of argon is 18. This means that each isotope has 18 protons and 18 electrons. Note that in isotopes, the mass numbers can change, but the atomic number always remains the same. It is only the number of neutrons that can change.

How many neutrons are in Argon 41?
A normal Argon atom has 18 electrons, 18 protons, and 22 neutrons.
How many electron shells does Argon have?
Argon has three electron shells. The third shell is filled with eight electrons. That is why it does not easily combine with other elements.
What has 9 protons and 9 neutrons?
Fluorine is a double loser with 9 protons and 9 neutrons.
How do u find neutrons?
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
What has 16 protons and neutrons?
(b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32.

How many neutrons does Argon 37 have?
Chlorine-37 has 17 protons and 20 neutrons in its nucleus, whereas argon-37 has a nucleus comprising 18 protons and 19 neutrons.
How many protons does Gallium 70?
Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of gallium-70 (atomic number: 31), an isotope of this element. The nucleus consists of 31 protons (red) and 39 neutrons (orange).
How many 3s electrons are in argon?
Since the 3s if now full we’ll move to the 3p where we’ll place the remaining six electrons. Therefore the Argon electron configuration will be 1s22s22p63s23p6. Because the third energy level has eight electrons and is therefore full (3s23p6) it is called a noble gas.

What is argon 18 electron configuration?
Element | Atomic number | Electron configuration |
---|---|---|
argon | 18 | 1s22s22p63s23p6 |
Can argon have more than 8 valence electrons?
Meaning that after the 3p orbitals are filled, the 4s orbitals will fill next, as they are in a lower energy state than the 3d ones. So yes, argon can have 18 electrons in its 3rd shell, but the 4th shell will gain 2 electrons first, and this is a large energy jump, therefor making argon stable.
When full the innermost electron shell of argon contains how many electrons?
Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost shell. The innermost shell has a maximum of two electrons but the next two electron shells can each have a maximum of eight electrons.
What element has 10 protons 10 electrons and 10 neutrons?
Neon symbol is Ne, atomic number 10 that locate in 2 period of noble gas group. Ne has 20.1797 atomic mass, 10 electrons and protons, 10.1797 neutrons, electron configuration is [He]2S22p6. Neon, Ne, discovered in 1898 by Sir William Ramsay, is a colorless noble gas.
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 element has 9 protons 11 neutrons and 10 electrons?
Explanation: By looking at the periodic table, you will see that Fluorine has 9 protons.
How do you find neutrons and electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What is proton neutron and electron?
Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.
