Q. Is the sun a nucleus?
The most abundant atom in the Sun is hydrogen. Each hydrogen atom is made up of a nucleus that contains a positively charged proton, and a remote, negatively charged electron that orbits the nucleus. In the Sun, collisions rip the hydrogen atoms apart, and separate the electron from the nucleus.
Q. How is an atom similar to the solar system?
According to the Bohr or solar system model of matter, every atom consists of a nucleus with a certain number of electrons rotating about the nucleus in their orbits. This is similar to the configuration of a solar system, with a large sun in the center and planets rotating in orbits around the sun.

Q. Is the nucleus heavy or light?
The size (diameter) of the nucleus is between 1.6 fm (10−15 m) (for a proton in light hydrogen) to about 15 fm (for the heaviest atoms, such as uranium). These sizes are much smaller than the size of the atom itself by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).
Q. How big is a nucleus compared to an atom?
The diameter of a nucleus is about 2 × 10 -15 m and the diameter of an atom is 1 × 10 -10 m.
Q. Which is bigger atom or particle?
In physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact.
Q. Which particle is the least massive?
Electrons
Q. Which atoms has the most mass?
The lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol.
Q. Does the nucleus have a positive charge?
The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Q. How photons are created?
A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics.
Q. Are Photons Real?
They’re real. We can make electrons (and positrons) out of photons in pair production. And you are made out of electrons and other particles that are equally real. Photons exist and best described as packets of energy or particles.
