I believe that it would be false. <span>The name of the ion P3- is not phosphoride ion but it is phosphide ion. </span><span>The </span>phosphide ion<span> is P </span>3−<span>, and </span>phosphides<span> of almost every metal in the periodic table are known. They exhibit a wide variety of chemical and physical properties. Hope this answers the question.</span>
The process by which gasses spontaneously move from an are with higher concentration to one of lower concentration is called diffusion. This process mainly occurs in gases and liquids. The end result of diffusion is called dynamic equilibrium. It is a complete mixing of the molecules of the gas.
Answer:
1. 1
2. 2
3. 6
4. 8
Explanation:
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
1. Li is the symbol for the chemical element known as Lithium: it has 1 valence electron. The electronic configuration of lithium is 1s²2s¹
2. Mg is the symbol for the chemical element known as Magnesium: it has 2 valence electrons. The electronic configuration of magnesium is 1s²2s²2p63s²
3. O is the symbol for the chemical element known as Oxygen: it has 6 valence electrons. The electronic configuration of magnesium is 1s²2s²2p⁴.
4. Ne is the symbol for the chemical element known as Neon: it has 8 valence electrons.
A. Would be the correct answer :-)
