The model below shows an atom of an element. 10 light gray and 8 dark gray balls sit at the center with 2 concentric black rings
MA_775_DIABLO [31]

Answer:

The Atomic Number of the atom of an element whose model is given is "8" that is option no. 'C' in the question.

Explanation:

An Atom comprises of 3 basic structures that are Protons, Neutrons and Electrons. The central part is the Nucleus which contains protons and neutrons having positive charge and no charge respectively. The electrons are revolving around the nucleus in electronic shells having the negative charge.

<u><em>ATOMIC NUMBER: </em></u>

Atomic number is the number of protons present inside the nucleus of an atom and it determines the place of that particular atom in the <u>Periodic Table.</u>

In the model, given in the question, the nucleus contains 2 types of balls dark gray colored and light gray colored. The key at the bottom shows the dark gray colored ball as having a positive charge and thus it represents the atomic number for the given atom of element which is <u><em>EIGHT (8).</em></u>

So, the atomic number for the given atom is 8 which is element OXYGEN.

How many milliliters of 0.121 M HCl are needed to neutralize 44.3 mL 0.274 M Ba(OH)2? Write the equation and don't forget to bal
Sergeeva-Olga [200]

Answer:

100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂

Explanation:

This is the chemical equation:

2HCl + Ba(OH)₂  →  BaCl₂ + 2H₂O

Formula for neutralization is:

Molarity of acid . Volume of acid = Molarity of base . Volume of base

0.121 . Volume of acid = 0.274 . 44.3

Volume of acid = (0.274 . 44.3) / 0.121 → 100

1 Select the correct answer! Which statement best explains the octet rule? A. Atoms gain, lose, or share electrons to achieve a
Ostrovityanka [42]

Answer:

A. Atoms gain, lose, or share electrons to achieve a full valence shell

Explanation:

The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.

  • In this process bonds are formed when there is an attraction between the two substances.
  • For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation.
  • Covalent compounds, form by sharing of electrons.

Therefore, the octet rule is attained when atoms gain full valence configuration.
