For which of the following elements would the most common ion be expected to have a larger radius than that of its corresponding

Andre45 [30]

Answer: The ion that is expected to have a larger radius than the corresponding atom is chlorine.

Explanation:

There are two types of ions:

Cations: They are formed when an atom looses its valence electrons. They are positive ions.
Anions: They are formed when an atom gain electrons in its outermost shell. They are negative ions.

For positive ions, the removal of electron increases the nuclear charge for an outermost electron because the outermost electrons are more strongly attracted by the nucleus. So, the effective nuclear charge increases for cations and thus, the size of the cation will be smaller than that of the corresponding atom.

For negative ions, the addition of electron decreases the nuclear charge for an outermost electron because the outermost electrons are less strongly attracted by the nucleus. So, the effective nuclear charge decreases for anions and thus, the size of the anion will be larger than that of the corresponding atom.

For the given options:

Option a: Chlorine

Chlorine gains 1 electron and form $Cl^-$ ion

Option b: Sodium

Sodium looses 1 electron and form $Na^+$ ion

Option c: Copper

Copper looses 2 electrons and form $Cu^{2+}$ ion

Option d: Strontium

Strontium looses 2 electrons and form $Sr^{2+}$ ion

Hence, the ion that is expected to have a larger radius than the corresponding atom is chlorine.

The Embargo Act of 1807 and the Neutrality Acts

insens350 [35]

The Embargo Act of 1807 and the Neutrality Acts of the 1930's were both attempts by the United States to avoid foreign conflicts. The correct option in regards to all the options given in the question is option "3". The Embargo Act of 1807 prohibited all kinds of exports from United states of America. This Act would treat any export as illegal. This Act was also intended to keep America from avoiding any conflicts with the warring nations. The Neutrality act was also intended towards remaining neutral towards all fighting nations.

13C and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particle

Degger [83]

6 electrons, 6 protons, and 8 neutrons.
This is because in isotopes of the same element proton and electron number are the same, it is only the number of neutrons that changes.
