How do the numbers of protons and electorns compare in a normal atom?
The atomic number, proton and electron are all the same amount in an element.
What circumstances is the molecular geometry around a central atom the same as the electron group geometry around the central atom?
The molecular geometry around a central atom is the same as the electron group geometry when there are no lone pairs of electrons on the central atom. In such cases, all electron groups (bonding pairs) are arranged symmetrically around the atom, leading to identical geometries. This typically occurs in molecules with linear, trigonal planar, or tetrahedral arrangements, depending on the number of bonding pairs.
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
Is the s orbital of an atom spherical?
Yes, the s orbital of an atom is spherical in shape. It has a uniform electron density distribution around the nucleus, meaning that the probability of finding an electron at a given distance from the nucleus is the same in all directions. This spherical symmetry is characteristic of all s orbitals, regardless of the energy level.
How do the numbers of protons and electorns compare in a normal atom?
The atomic number, proton and electron are all the same amount in an element.
When a sodium atom reacts with a chlorine atom to form a compound the electron configurations of the ions forming the compound are the same as those of noble gas atoms?
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
What makes a happy atom?
a happy atom is an atom with all its electron shells completely filled

Is an electron bigger then an atom?
No. An electron as a particle is small however the probability cloud of an electron can be large- most of the volume of an atom consists of the electron cloud. In relation to this the nucleus, although it contains nearly all of the mass of the atom, is quite small.

Is the Mass of hydrogen atom is about the same as a proton?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
Name given to all parts of the atom?
All the components of an atom (neutron, proton, electron) are called subatomic particles or elementary particles.
The volume of an atom is determined by the size of its?
It can be determined by the size of it's electron. The reason for this being is because of the mass that is calculated by the protons to the neutrons of the atoms within the nucleus.
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
What does a fluoride ion have in common with a neon atom and a sodium ion?
what does an atom have in common with an ion?
