Factors that determine ionization energy:

  • Electronic Repulsion - If the electronic density decreases, the ionization energy with increase and vice versa. If an electron gets released, it decreases the electronic repulsion. This makes releasing another electron harder than the first on unless the electron that is being released comes from another energetic level.
  • # Of Energy Levels - The more energy cores that get filled up, the more ionization levels decrease. When we see the energy levels go from top to bottom, the ionization also go from most to least. This is why ionization occurs on the highest level.
  • Nuclear Charge - The higher the atomic number, the higher charge in the nuclei. This also makes the ionization energy higher as it increases from left to right of in other words, if the nuclear charge gets higer, the energy gets higher as well.

Factors that determine atomic volume:

  • How many protons are in the nucleus (nuclear charge)
  • How many energy levels carry electrons (electrons in outer energy level)

Best of Luck!

Consider the substances below.
ratelena [41]

Answer:

They have the same number of atoms. = YES

They have different masses. = YES

Explanation:

1 mol of beryllium

• 1 mol of salt

beryllium  = Be = Atomic mass: 9.012182

salt  = NaCl = Molar mass: 58.44 g/mol

1 mol of water

• 1 mol of hydrogen

water  = H2O = Molar mass: 18.01528 g/mol

hydrogen = H = 1g/mole

Which statement is true about these substances?

They have exactly the same mass. = NO

They have different numbers of particles = NO

They have the same number of atoms. = YES

They have different masses. = YES

Avogadro constant means the number of units in one mole of any substance (defined as its molecular weight in grams) is equal to 6.02214076 × 10^{23}.

1.0 mole of KCl(aq) is added to which solution to produce a precipitate?
taurus [48]

Answer:

Ag+

Explanation:

If you imagine as if the problem were double replacement, you would pair the Cl with one of the following ions provided in the choices. As seen on Table F, Ag+ paired with Cl- produces an insoluble compound, hence the precipitate. All the other ions shown in the multiple choice section, when paired with Cl- will produce a soluble compound, as a result NOT a precipitate.

How are elements similar to those in the same group on the periodic table ​
enot [183]

Answer:

All the members of a group of elements have the same number of valence electrons and similar chemical properties.

Explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
