How do we represent the element chlorine having mass number 35 and atomic number 17 mention the number of neutrons present in chlorine state its Valency?
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).
What element has a mass number of 35?
These atoms of chlorine have different atomic mass numbers. The isotope that has 18 neutrons has an atomic mass number of 35.
What element has atomic number 17 and mass number 37?
| General | Symbol 37 Cl | Names chlorine- 37, Cl-37 | Protons 17 | Neutrons 20 |
|---|
Is CL 37 radioactive?
| IT: Isomeric transition | p: Proton emission |

What has mass No 35 and 18 neutrons?
X will belong to period 3f as it has three shells. Since it requires one more electron to get stable gas electron configuration, so the valency is 1.
Which element has the atomic number 17?
Chlorine : the chemical element with atomic number 17.
How many electrons are there in a chlorine atom mass number 35 atomic number 17?
| Name Chlorine | Atomic Mass 35.453 atomic mass units | Number of Protons 17 | Number of Neutrons 18 | Number of Electrons 17 |

What element has the largest atomic mass?
The lightest chemical element is Hydrogen and the heaviest is Hassium . The unity for atomic mass is gram per mol.
How do we calculate atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu , you can calculate the mass of the atom.
Is there an atomic mass of 41?
| Atomic Number Symbol Name | 38 Sr Strontium | 39 Y Yttrium | 40 Zr Zirconium | 41 Nb Niobium |

What has 17 protons and 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 do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called Lanthanides . They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. ... The lanthanides are between Barium and Hafnium.
Which number is the atomic number?
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 .
