Answer:
proton-6
electron-6
neutron-7
Explanation:
it seems like you are taking about carbon 13 here
The relative mass of an electron is 1/1840 the mass of a C-12 atom. Hence, option B is correct.
<h3>What is an electron?</h3>
An electron is a negatively charged subatomic particle.
An electron is very small, about 1/1,837th the mass of a proton. Atomic Weights Atomic mass of an atom is expressed in atomic mass units (amu) which are approximately grams. A more conventional way of expressing the mass of an atom is Atomic Weight.
Atomic mass units are expressed relative to the atomic mass unit of an unbound neutral carbon-12 atom.
Hence, the relative mass of an electron is 1/1840 the mass of a C-12 atom.

Answer: To me its ductility and malleability
Explanation:
when she stepped on the melted gum it was flattened. But when she picked her foot up it stretched out, which to me is a thin sheet can be easily formed by hammering or rolling. For ductility it is the ability of a solid material to deform under tensile stress. The stress being her foot and the material is the gum.
Answer:
A =8
B =8
C = O oxygen
D =26
E =30
F = Fe iron
Explanation:
No of protons = atomic number
No of protons + number of neutrons = atomic mass
