In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
Argon-40 has 18 electrons. This is because argon has an atomic number of 18, which indicates the number of protons (and electrons) in a neutral atom of argon.
Argon has 18 electrons.
Argon-40 atom has 18 electrons.
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
The atomic number of argon is 18. So it has 18 electrons.
Argon-40 has 18 electrons. This is because argon has an atomic number of 18, which indicates the number of protons (and electrons) in a neutral atom of argon.
Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.
Argon has 18 electrons.
Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.
Argon-40 atom has 18 electrons.
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
Argon has 18 protons, 22 neutrons, and 18 electrons.
No, Calcium (Ca) has 20 electrons while argon has 18 electrons. Calcium has two more electrons than argon.
Ca2+ is one of them This is because the mass number of Argon (which is 18) lost 2 electrons (which has a negative charge). Without the impedance of the negative charge, Argon's mass number becomes 20 (instead of 18) and it acts like Calcium (which has the mass number of 20). You can probably figure out the rest of them from the above.
Argon has 18 electrons because it possesses 18 protons in its nucleus, making it electrically neutral. The number of electrons in an atom is equal to the number of protons in the nucleus.
