Ionization energy increases from left to right because the left wants to lose elctrons and the right wants to gain electron
As you go a group it is easier lose lose because the electrons are farther away from the nucleus and there is less attraction from the positive charges.
It should be 3p3. the p level can hold 6 electrons
Rubidium group 1, 1 valence electrons very reactive
Mg2,2 very reactive
Al 3, 3 reactive
Your arm looks similar to a chicken wing beneath your skin. Both contain a ton of cartilage.
Answer:
Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water. If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water. Therefore it would take .25 moles of sulfuric acid to react with .5 moles of sodium hydroxide.

Answer:
n = 3
Explanation:
Given the formula for the transition energy of an atom with 1 electron:
For the H transition n=5 to n=2:
Then we solve for nf with Z=2 (Helium)
Is near 3, actually the energy of the transitions are:
H (5⇒2) = -2.85 eV = 434 nm (Dark blue)
He (4⇒3) = -2.64 eV = 469 nm (Light blue)
I thought it was cool to see the actual colors. Included them.
Answer:
- Form crystals.
- HIgh boiling point and melting points
- Bad conductors of electricity
- High hardness
Explanation:
Just a brief introduction to remember what the <em>ionic compounds</em> are. Ionic compounds are the compounds formed by ionic bonds, i.e. the eletrostatic attraction between cations (positivie ions) and anions (negative ions). The ionic compounds are mostly either oxides or salts. An example of an ionic oxide is CaO, and an example of an ionic salt is NaCl.
The strength of the ionic bonds is responsible for most of the characteristics of these compounds. These are the most common <em>characteristics that solid ionic compounds share</em>:
- They form cristals: the ionic compounds form long networks of atoms very organized, instead of individual units. That is why you must not refer to these compounds as molecules.
- HIgh boiling and melting points: because high energy is required to separate the ions, and form the new state.
- Bad conductors of electricity: since the ions are in fixed position, they do not carry charges (the charges are not moving), so in solid state, the ionic compounds are bad conductors (but in aqueous solution they are very good conductors).
- Hardness: crystals are relatively hard and when they are hammered they brake apart.
