What are the 5 postulates of the particle theory of matter?
The postulates of John Dalton: 1. All matter is made up of atoms. These are the ultimate particles, and are indivisible and indestructible. 2. All atoms of a given element are identical, both in weight and in chemical properties. 3. Atoms of different elements have different weights and different chemical properties. 4. Atoms of different elements can combine in simple whole numbers to form compounds. 5. When a compound is decomposed, the recovered atoms are unchanged and can form the same or new compounds.
Borons atomic number?
Borons atomic no. is 5...
What is the atomic number and mass of boron?
Atomic Number = 5 Atomic Mass = 10.811
What is the atomic number of an atom with mass number 9 and 5 electrons?
The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5
What is the atomic mass number of an isotope that has a atomic number of 6 but atomic mass of 5?
I think your understanding is confused. Atomic No. of '6' indicates the position in the periodic table, the number of protons, and the number of electrons. Atomic Mass is a number ( equal to or greater than atomic no.), which is the the total of protons and neutrons in the nucleus of an atom . So you atomic mass of '5' is incorrect as it is less than '6'. I think you mean 5 neutrons. If so the atomic mass is 6 + 5 = 11 This would be the isotopic element C-11 (Carbon eleven).
Why is Chlorine the only element that has a 5 atomic mass?
Chlorine does not have atomic mass 5, so it cannot be "the only element that has a 5 atomic mass".
5 levels that euclid used in organizing geometry?
1. Undefined Terms 2. Definitions 3. Postulates 4. Conjectures 5. Theorems :)

How tall is Tonjia Atomic?
Tonjia Atomic is 5' 6".
Which atom has atomic number 5?
Boron is a non metal element. Atomic number of it is 35.
What is the atomic mass number of an isotope with atomic number 5 and includes 6 neutrons?
Basic arithmetic (5+6) suggests that the atomic mass is eleven.
