The number of protons is equal to the atomic number and the element with the atomic number 17 is Chlorine.
If you check atomic masses in the periodic system you will find quite often that the value is higher than you would have expected from the sum of proton -, neutron-, and electron - masses minus mass defect. For example chlorine has 17 protons and assuming that there are 18 neutrons, the Atomic Mass of chlorine should be approximately 35 amu (you could calculate the exact expected value, neglecting the mass defect or mass loss caused by the formation of the nucleus) However, the actual atomic mass of chlorine is 35.4527 amu.
The reason for this is that chlorine occurs in nature in two different forms. One form has 17 protons and 18 neutrons, the other form has 17 protons and 20 neutrons. Atoms with the same number of protons but different number of neutrons are called isotopes

Which element from the periodic table has 17 electrons?
Chlorine!!! Chlorine has two stable isotopes ; Cl-35 & Cl-37 The subatomic particle arrangemtn in them is Cl-35 ; 17 protons, 18 neutrons, 17 electrons Cl-37 ; 17 protons, 20 neutrons, 17 electrons.
If an element has 12 protons and 17 neutrons how many electrons must it have?
The number of electrons in a neutral atom is equal to the number of protons, so in this case, the element must have 12 electrons.
How many protons neutrons and electrons are in chlorine 37?
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
How many protons neutrons and electrons are in cl?
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
What is the correct number of protons electrons and neutrons in the isotope 36Cl respectively?
Protons = 17; Electrons = 17; Neutrons = 19
How many electrons does an element have if it has 17 protons and 18 neutrons?
If an element has 17 protons, it will also have 17 electrons since atoms are electrically neutral. Adding the number of neutrons (18) to the number of protons (17) gives us the mass number of the element, which in this case would be 35.
Which element from the periodic table has 17 electrons?
Chlorine!!! Chlorine has two stable isotopes ; Cl-35 & Cl-37 The subatomic particle arrangemtn in them is Cl-35 ; 17 protons, 18 neutrons, 17 electrons Cl-37 ; 17 protons, 20 neutrons, 17 electrons.

17 protons 22 neutrons 17 electrons
If an element has 12 protons and 17 neutrons how many electrons must it have?
The number of electrons in a neutral atom is equal to the number of protons, so in this case, the element must have 12 electrons.
How man protons neutrons and electrons does 35Cl- have?
35Cl- has 17 protons, 18 neutrons, and 18 electrons. The negative charge indicates an extra electron compared to the number of protons.
How many protons neutrons and electrons are in chlorine 37?
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
What element has 18 neutrons in its atom?
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
How many protons and electrons and neutrons does the element chloride have?
Protons=17 Neutrons depend on isotope but most common is 18, and electrons depend on compound however by it self cl has 17 but it steals an electron from other elements to get 18
How many protons neutrons and electrons are in cl?
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
How many protons does the element chlorine have?
Chlorine (Cl) has atomic number 17, and so it has 17 protons in the nucleus.
What is the correct number of protons electrons and neutrons in the isotope 36Cl respectively?
Protons = 17; Electrons = 17; Neutrons = 19
How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?
17 electrons. The number of protons and electrons is always the same.
