What has 18 protons and 20 neutrons?
What has 18 protons and 20 neutrons?
calcium
Explanation: You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….
What atom has 18 protons 21 neutrons?
What element has 18 protons and 21 neutrons? – Quora. That would be an isotope of the noble gas argon, Ar, since the element has 18 protons — atomic number 18. Specifically, this is argon-39 or 39/18Ar, if you prefer.
How many protons neutrons and electrons are in an 18 o?
18O2− has 8 protons, 10 neutrons, and 10 electrons.
How many neutrons are in C 18?
Each carbon atom has the same number of protons and electrons, 6. C has 6 neutrons, 13C has 7 neutrons, and 14C has 8 neutrons and so on. Since there are a variety of carbon isotopes we must specify which C atom defines the scale….
| Isotope | Atomic Mass amu | Natural Abundance % |
|---|---|---|
| 18O | 17.99916 | 0.204 |
What has 18 protons and 17 neutrons?

What element has 18 protons and a mass number of 40?
Argon
Argon is the 18th element on the periodic table. One isotope of argon has an atomic mass of 40. How many protons, neutrons, and electrons are in a neutral argon-40 atom?
What has 17 protons and 18 neutrons?
Chlorine-35
Chlorine-35 has 17 protons and 18 neutrons. It’s considered a stable isotope and is the most abundant isotope of chlorine, with approximately 76%…
Which has 18 electrons when it is a neutral atom?
Argon has 18 protons and is a neutral atom, so it also has 18 electrons.
How many neutrons are in o 18?
10 neutrons
All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons. “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.
Which element has 18 protons?
The element having 18 protons is Argon. The number of neutrons and electrons are not necessary in identifying what an element is.
What has 18 protons and 15 electrons?
Protons are positively charged, while electrons are negatively charged. If the ion has 18 protons and 15 electrons, it has 3 more protons than electrons, therefore, the ion has an overall positive charge of 3+.
What atom has 17 protons 18 electrons and 18 neutrons?
Unlike protons or neutrons, electrons have no mass. 14 protons, 14 electrons 2. Answer to: A chlorine atom has 17 protons, 18 neutrons, and 17 electrons. What is the atomic number of chlorine? How many protons and electrons are present in the mg2 + ion? 12 protons, 10 electrons 3. As we know electron and proton charge is equal and opposite.
What ion has 20 protons and 18 electrons?
When the number of protons differs from the number of electrons, you have an ionic charge. A Calcium atom with 20 protons and 18 electrons has a charge of 2+ because it has 2 extra protons, which have a positive charge. A charged atom is called an ion. When the charge is positive, it is called an cation.
