atom: john Dalton
15 electrons and 15 protons
6 electrons and 6 protons
6 protons and 6 electrons
Protons do not contain electrons. Protons are positively charged, electrons negatively charged.
35 protons, 36 electrons
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
Indium has 49 protons and electrons.
Protons=electrons=33
Yes , the no. of electrons is equal to the no. of protons
Protons and electrons cannot be disintegrated.
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
Protons and electrons have mass and charge.
