Using electronegativity difference is a good guide to the ionic/ covalent nature. Large differences indicate greater ionic character, small differences more covalent character. The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have. 
Ionic bonding is formed through electrostatic attraction between a cation and anion. Foe example, Sodium fluoride has ionic bonding because it is composed by sodium and Fluorine (a non metal). On the other hand, covalent bonding is characterized by atoms sharing pairs of electrons. For example; methane has covalent bonding; carbon has 4 valence electrons and hydrogen has 1; when they bond they have a total of 8 electrons and satisfies the octet rule.

Equal masses of gaseous N2 and Ar are placed in separate flasks of equal volume at the same temperature. Tell whether each of th
Hoochie [10]

Answer:

c. The N2 molecules collide more frequently with the walls of the flask than do the Ar atoms.

Explanation:

The statements are:

a. There are more molecules of N2 present than atoms of Ar. <em>FALSE</em>. Because 1 mol of molecules of N2 = 28g and 1 mol of molecules of Ar = 40g. As there are equal MASSES, you will have more molecules of N2 than Ar molecules

b. The pressure is greater in the Ar flask. <em>FALSE</em>

Because pressure is directly proportional to amount of molecules. As molecules N2 > Molecules Ar. The pressure is greater in N2 flask

c. The N2 molecules collide more frequently with the walls of the flask than do the Ar atoms. <em>TRUE</em>

The collision probability of N2 is higher because there are more molecules presents

What does the kinetic theory state about the relationship between the speed and temperature of gas molecules?
mario62 [17]

The kinetic theory state about the relationship between the speed and temperature of gas molecules "As the temperature increases, the speed of gas molecules increases".

<u>Option: </u>C

<u>Explanation:</u>

The temperature relates to a gas, according to the kinetic theory of gases, influences the rate of motion of the gas particles. The higher the gas temperature, the faster the gas particles are moving; the reverse is true, too.

This is because the gas particles gain more kinetic energy as the temperature of the gas increases, and therefore move faster and collide more with each other and the container walls.The rate of a gas's molecules is proportional to the temperature, and is inversely proportional to the gas's molar mass.

Elements in group 16 want to bond with elements in group ___.
Trava [24]

Answer:

Two

Explanation:

Elements in group 16 wants to bond with elements in group IIA, the group of alkaline earth metals.

  • The bonding will make it easier for them complete their octet.
  • Elements in group 16 has 6 valence electrons.
  • To have a complete octet, they require 2 more electrons.
  • Group II elements are willing donors as they are metals.
  • For Group II elements to fill their octets, they must lose two electrons.
  • So the willingness of group II elements to lose two electrons and the readiness for group 16 elements to gain the electrons makes the desire one another.
