What does it mean to say that an atom is an exited state?
When an atom is in an excited state, it means that its electrons have absorbed energy and moved to higher energy levels. This can happen through processes like absorbing light or collisions with other particles. The electrons do not stay in this state indefinitely and eventually return to their original, lower energy levels by releasing the absorbed energy in the form of photons.
When you say an electron is in its ground state what does that mean?
when something is in the ground^No. That is totally incorrect.Basically, a ground state electron is when the atom/element is not being surged through with heat or electricity. Basically, it's the atom's normal electron configuration. So NA [Sodium]'s ground state would be shown as : 1s2, 2s2, 2p6, 3s1.The opposite is when it's in it's excited state. You can remember tell when an atom is in it's excited state when in the electron configuration, there is a huge jump, like 1s2,2s2,2p5, 3s2. This might have happened due to being exposed to heat and or electricity.In other words, ground state=normal, excited is, well, excited. XD
To say that energy levels in an atom are discrete is to say the energy levels are well defined and?
quantized, meaning they can only have certain specific values. This quantization results in distinct energy levels for electrons in an atom, leading to the emission or absorption of photons when electrons transition between these levels.
Why are energy levels of hydrogen atom less than zero?
This doesn't really mean the electron has negative energy or energy less than zero. It is merely a matter of convention and the way the energy equation is written. "Because it takes a minimum amount of energy, called the "ionization energy" to strip or ionize a bound electron from the Hydrogen atom, energy levels are usually referred to as being negative quantities. In both classical physics and quantum mechanics the absolute value of energy is irrelevant; only energy differences matter. It is convenient to say that when ionized the electron will have zero binding energy to the proton. With this convention, the different energy levels of a Hydrogen atom are given by the equation: E = - E (z)/n^2 (notice that negative sign in the equation) where E(z) = 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV." Simple as that.
If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons would Bohr say the atom has A. 41 B. 80 C. 121 D. 201?

What does is mean to say that an atom is in an excited state?
When an atom is in an excited state, it means that its electrons have absorbed energy and moved to a higher energy level farther from the nucleus. This higher energy level is unstable, and the electron will eventually return to its original energy level by emitting a photon of light.

When an atom is in an excited state, it means that its electrons have absorbed energy and moved to higher energy levels.

What is meant by isolated gaseous atom and why this term is used in case of ionization energy?
ionization enthalpy means the energy required to remove an electron from isolated gaseous atom in its ground state . the isolated gaseous state is the state in which no other force of attraction acting on an atom form other atom . so that, we get the exact energy required to romove or add an electron to an atom. and here ground state is used to say that electron are stable and are not exited .. so , the ionization enthalpy is the energy required to remove an electron from gaseous atom which is free from other atom in that state in which electrons are stable. by shashank
What is difference between a ground state electrons configuration and an excited state configuration?
In the ground state all the (only one for Hydrogen)) electrons is in the lowest stable orbit. If the electron gains energy (usually from a photon) it will orbit in a higher energy state (called excited).

Ground state vs excited state?
A ground state is an outer orbital electron of an element that is at its lowest possible energy level. The electron in an excited state has a higher energy level than a ground state electron. The average distance from the nucleus is greater in the excited state than in the ground state.

quantized, meaning they can only have certain specific values. This quantization results in distinct energy levels for electrons in an atom, leading to the emission or absorption of photons when electrons transition between these levels.

What do we mean when we say that energy levels in atoms are quantized and how does this concept impact the behavior of electrons within an atom?
When we say that energy levels in atoms are quantized, we mean that electrons can only exist at specific energy levels and cannot exist between these levels. This concept impacts the behavior of electrons within an atom by determining the specific orbits or shells they can occupy, leading to the formation of distinct energy levels and the emission or absorption of specific amounts of energy when electrons move between these levels.

What did Planck say about energy and electron?
He said that electrons can become excited and begin to hop energy levels; when this happens an electron is in the excited state.
