What is the atomic number of an element with 9 protons and 10 neutrons and 9 electrons?
For example, a fluorine atom has 9 protons and 10 neutrons. Its atomic number is 9, while its atomic mass is 19 atomic mass units. So we can say that its atomic weight is 19, or its mass number is 19.Apr 1, 2020
What has 18 protons and 22 neutrons?
Argon has the chemical formula Ar. Argon has 18 protons and 22 neutrons in its nucleus giving it an Atomic Number of 18 and an atomic mass of 40. Argon is a Noble Gas.
Which isotope 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….Dec 13, 2017
What isotope has 17 electrons and 18 neutrons?
A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.
What has 12 protons and 12 neutrons?
The symbol for magnesium is . Magnesium has an atomic number of 12 and a mass number of 24. So a magnesium atom has 12 protons, 12 electrons, and 12 neutrons.
What is the element with 20 protons and 20 neutrons?
Calcium has 20 protons and 20 neutrons.
Why is chlorine with 17 protons 18 neutrons and 18 electrons a negatively charged ion?
Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1.
What element has 16 protons and 18 neutrons?

How do you find the electrons?
Finding the Number of Electrons
The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.3 days ago
What is the mass number of an atom with 17 protons 18 neutrons and 17 electrons?
Mass number= 17+ 18 =35.
How do you find neutrons and electrons?
Calculating numbers of subatomic particles
To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number. number of neutrons = mass number – atomic number.
Is proton and neutron the same?
Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).Jul 1, 2019
How a neutron is formed?
A neutron is formed by an electron and a proton combining together and therefore, it is neutral.
What is the difference between chlorine-35 and 37?
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). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.
How many protons electrons and neutrons are in CL 35?
Chlorine is an element with unique properties
