What is the symbol for an ion with 16 protons and 18 neutrons?
We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
What element has 18 protons and 21 neutrons?
#18 – Argon – Ar.
What is the symbol for an ion having 15 protons and 18 electrons?
P (Phosphorus) has an atomic number of 15. Therefore, it has 15 protons. A charge of -3 indicates that it has gained 3 electrons. Therefore, it has 18 electrons.
Which species has 16 protons 18 neutrons and 18 electrons group of answer choices?
If a species has 16 protons, 18 electrons and 16 neutrons, then the symbol of species of is S2−.
What is the symbol of an ion with 15 protons 18 neutrons and 18 electrons?
By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31. Because the ion has 15 protons and 18 electrons (three more electrons than protons), its net charge is 3-.
What is the exact numerical charge of an ion with 16 protons and 18 electrons?
The atomic number of sulfur is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
Which element contains 15 neutrons?
element phosphorus (P)
What is the charge of a particle having 21 protons and 18 electrons?
The atomic number is 21, which means that scandium has 21 protons. While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge. This means it has 3 fewer electrons than the neutral atom or 21 – 3 = 18 electrons.
What is the symbol of an ion with 20 protons 20 neutrons and 18 electrons?
Ca2+ represents an ion with 20 protons and 18 electrons.
What is the atomic number of an ion with a 2 charge when it has 18 electrons?
Explanation: A certain element forms an ion with 18 electrons and a charge of +2. Recall that atoms have the same number of electrons as protons, and the atomic number of an atom is the number of protons it has. So, the atom in question is the atom whose atomic number is 20…..that’s calcium (Ca).
What is the charge of an ion that contains 17 protons and 18 electrons?
Whereas, the charge of the atom is solely determined by the electrons and protons in the atom. In the question, the number of protons is 17 and the number of electrons is 18. Since, there is an extra electron in the atom, it carries a charge of −1 . So, the correct answer is C.
What is the symbol of ion with 17 protons and 18 electrons?
chloride ion
What is the mass number and atomic number of a chlorine atom that has 17 protons and 18 neutrons?
35
What will be the charge of magnesium when it becomes an ion?
2+
