What is the mass number and atomic number of chlorine?
4 rows · May 01, 2020 · Identify the mass number and atomic number of a chlorine atom that has 17 protons and ...
How many protons and electrons does chlorine have?
Aug 25, 2014 · The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
What is the chemical symbol for chlorine?
An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). The number of electrons in an atom's outer shell determines the atom's chemical properties.
What is an isotope of chlorine?
Jan 10, 2012 · The number of protons in chlorine is 17 and the number of neutrons is 18 since the atomic mass of chlorine is 35
What is the atomic mass of chlorine contains 17 protons and 18 neutrons?
35 amu
However, three out of four chlorine atoms weigh 35 amu (17 protons and 18 neutrons) and the fourth weighs 37 amu (17 protons and 20 neutrons). These are the isotopes of chlorine. The atomic weight reported in the periodic table is the average weight of 35.5 amu.
What is the mass number of an atom with 17 protons 17 electrons and 18 neutrons?
Answer: 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).Apr 22, 2021
What element has 17 protons and 18 neutrons?
chlorine atom
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 name of the element with 17 protons 18 neutrons and 18 electrons?
chlorine
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.Aug 15, 2020
Table we see the atomic number that's 17. So the atomic number for chlorine is always going to be 17MoreTable we see the atomic number that's 17. So the atomic number for chlorine is always going to be 17. Doesn't matter what isotope we have the atomic number that's equal to the number of protons.
How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is the mass number of an atom with 17 protons 17 electrons and 20 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.
Does chlorine have 17 neutrons?
Chlorine has two common isotopes, Chlorine-35 and Chlorine-37. Chlorine-35 has 17 protons and 18 neutrons and occurs in nature about 75% of the time. Chlorine-37 has 17 protons and 20 neutrons and occurs in nature about 25% of the time.Oct 15, 2003
Why is chlorine with 17 protons 18 neutrons and 18 electrons a negatively charged ion?
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 element has 18 protons and 18 neutrons?
Meaning. Argon is a Group 0 element, on the Periodic Table, with 18 protons in the nucleus.
What is the element name for 18 protons 20 neutrons and 18 electrons?
Calcium
The Correct Answer is Calcium. Atomic number is defined as the number of protons or the number of electrons that are present in an electrically neutral atom. Thus, At.
Neutron and Mass Numbers and Nuclear Properties
Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1.
Neutron and Atomic Numbers and Nuclear Stability
Nuclear stability is a concept that helps to identify the stability of an isotope. To identify the stability of an isotope it is needed to find the ratio of neutrons to protons. To determine the stability of an isotope you can use the ratio neutron/proton (N/Z).
