Which group of elements has very high ionization energies and very low electron affinities?
Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. Ignoring the noble gases, however, group 7 halogens (F, Cl, Br, I, etc.) have the highest first ionization energy. That's because these elements have seven valence electrons, and they don't want to give up any electrons - they want another one!
Electrons in second energy level of an atom?
If you want to learn how many electrons to accommodate in energy shells. Use the formula 2n2 where n stands for the no of shell. Like in second shell= 2(2)2=2x4=8. It means eight electrons can be accommodated. it is the most appropriate method to accommodate first 18 elements.
How is chemical energy converted into light energy?
As a chemist I can tell you that you have witnessed chemical energy being converted to light energy everytime you see a light bulb powered by a battery. The energy in the battery is stored as chemical energy, which is released by electrons leaving chemicals and flowing through the filament in the light bulb. As the electrons flow through the filament, they release some of their energy in the form of light. That is a rather simplified explanation, but if you want more detail, you better learn some indepth chemistry and physics first.
What would be the charge of zinc when it loses an electron?
The charge of the ion formed is the eat my a ss hole Answers.com sucks d ick.
What do all atoms want?
They all want 8 electrons!
Do the elements form anion have high or loe ionization energy?
low ionization energy
Do you need your security license before you apply to a company you want to work with?
It depends on the company and the position you are applying for. Generally, no you do not.
How does solar energy happen?
Solar Energy happens when you put a solar energy panel in a sunny position and when the sun shines on it. It should start working to what ever you want it to work on!
How the electrons are arranged around nucleus an how they affect its reactivity?
Electrons are arranged in electron clouds around the nucleus. The reactivity is determined by the number of valence electrons, or electrons in the outermost energy levels. All atoms (except for hydrogen who wants 2 electrons and boron who wants 6) want 8 valence electrons, or a full outer energy level. This makes them stable (like the noble gases). If an atom has 1 valence electron it will desperately want to lose that electron while an atom with 7 electrons will want to gain one electron. All atoms have the goal of 8 valence electrons. Also, the 1st energy level only has 2 electrons. After that there is 8 electrons (approximately, because you can never truly determine where an electron is inside of an atom at any given time).
Which best explains why the noble gases are chemically unreactive?
because the most an atom can have in its outer energy level for electrons is 8 and noble gases have 8 the do not want to react because they want to keep the "octet". reacting means gaining or losing electrons
What heppens when a atom gains or loses electrons?
When an atom gains or loses electrons, it gains a negative or positive charge respectively. Atoms generally try to gain enough electrons to fill their outer, valence electron shell. For the first shell the number of electrons is 2 and for all others, atoms usually want 8 electrons.
Which of the semi-metals that have their valence electrons in the fouirth energy level has the largest ionizatiuon energy?
Arsenic (As)The semi-metals are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium. The fourth energy level is simply four down the rows. This means the semi-metals that have their fourth energy level are Germanium and Arsenic. Since Arsenic has more electrons in it's outer shell, it will not want to give away electrons as much as Germanium.
What is needed for electrons to pull away from atoms?
you need two atoms depending how many electrons they want to get or get rid of like water hydrogen wants to give away one electron and oxygen wants to get two electrons that is how it becomes H2O
Why is eight the maximum number of electrons any atom can have?
It isn't. Electrons surrounding atoms are arranged in energy levels. Each energy level can carry a certain number of electrons. The innermost energy level can hold up to two electrons, the second and third levels have up to eight each, the fourth has a capacity of 16... If ever an atom (such as a noble gas) or an ion has a full outer shell, it is considered stable unreactive and, for want of a better word, "happy".
Why in the world would an atom want to become stable?
Atoms are not sentient. They undergo chemical bonding and chemical reactions in order to have lower energy, which makes them stable. Typically this means either sharing electrons to get an octet of electrons, or transferring electrons so they get an octet of electrons. This is not a conscious decision on their part.
Why are noble gases nonreactive?
This is because they have a complete valence shell.Noble gases are closer to being stable in terms of their electrons than other elements, thus making them less inclined to react with other elements.
