The electron cloud model says that we cannot know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas. These areas are specified by orbitals. The orbitals are specified by shells and sub-orbitals. In the Bohr model, electrons are assigned to different shells.
Q. Which statement describes the earliest model of the atom Brainly?
Explanation: The ‘Atomic Theory’ of Dalton is characterized as the earliest model(came in 1803) which described the atoms as the indivisible and resistant spheres.

Q. What happens when the electron moves from the first?
What happens when the electron moves from the first energy level to the second energy level? Energy is absorbed, and an emission line is produced. Energy is released, and an emission line is produced.
Q. What can you assume has happened if an electron?
What can you assume has happened if an electron moves to a higher energy level? The atom has become more stable. The electron has lost energy. The atom in the ground state has less energy and is less stable than the atom in an excited state.
Q. What causes an atom to lose an electron?
Atoms lose electrons by a process called ionic bonding. In this way the metal atom forms what is called a cation which is just a positively charged ion. The process is called ionization and the energy involved in the process – providing that the atom and the ion are gaseous – is called the ionization energy.
Q. What happens if an atom loses all its electrons?
Final answer :- if the atom loses all its electron then it get change into positively charged ion. example :- if you take the example of Alpha particles, then we will notice that it is the positively charged Helium atom without a single electron.
Q. What is it called when an atom loses electrons?
When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation.
Q. Why atoms tend to gain or lose electrons?
Q. Why atoms tend to gain or loss electron? Atoms tend to gain or loss electrons in order to attain their nearest noble gas configuration and the completion of their octate helps them gain stability.
Q. How do electrons exist?
In 1913, Danish physicist Niels Bohr postulated that electrons resided in quantized energy states, with their energies determined by the angular momentum of the electron’s orbit about the nucleus. The electrons could move between those states, or orbits, by the emission or absorption of photons of specific frequencies.
