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%…
What has 17 protons and 18 neutrons and 18 electrons?
17 protons, 18 neutrons, 18 electrons
This is a
chloride ion
. According to the periodic table, there are 17 protons because the element is chlorine.
What element has 17 protons and 18 neutrons?
Every
chlorine
atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.
What is the number of electrons in an atom that has 17 protons and 18 neutrons?
| Name Chlorine | Atomic Mass 35.453 atomic mass units | Number of Protons 17 | Number of Neutrons 18 | Number of Electrons 17 |
|---|
What element has 16 protons and 18 neutrons?
The atomic number of
sulfur
is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
Why does chlorine have 18 neutrons?
An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has
a mass number of 35
which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
What has 18 protons and 19 neutrons?
#18 –
Argon
– Ar.
What is the charge of 17 electrons?
Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the
overall charge is zero
. Once the chlorine gains an electron, however, the total just becomes -1 since there are now 18 electrons and still 17 protons. As a result chlorine is a negative charged ion.
What is the net charge if there are 17 protons and 18 electrons?
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a
net negative (–1) charge
.
What is the symbol for a chlorine atom that has 17 protons 18 neutrons and 18 electrons?
For example, the atomic mass of chlorine (
Cl
) is 35.45 amu because chlorine is composed of several isotopes, some (the majority) with an atomic mass of 35 amu (17 protons and 18 neutrons) and some with an atomic mass of 37 amu (17 protons and 20 neutrons).
What has 4 protons and 3 neutrons?
Lithium
, for example has three protons and four neutrons, leaving it with a mass number of 7.
Is chlorine a single atom?
2.8. Elements can be made of
one
atom, like He, or be elemental molecules, such as hydrogen (H
2
), oxygen (O
2
), chlorine (Cl
2
), ozone (O
3
), and sulfur (S
8
). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
What has 18 protons and 20 neutrons?
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 is the number of protons equal to?
The number of protons in the nucleus of the atom is equal to
the atomic number (Z)
. 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.
Why chlorine is not a whole number?
For example, the
relative atomic mass of chlorine is 35.5
rather than a whole number. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37.
