Identify each of the following elements:

(a) a halogen whose anion contains 36 electrons,

(b) a radioactive noble gas with 86 protons,

(c) a Group 6A element whose anion contains 36 electrons,

(d) an alkali metal cation that contains 36 electrons,

(e) a Group 4A cation that contains 80 electrons.

Answer:

For a: The correct answer is

and For b: The correct answer is Radon.

For c: The correct answer is

and For d: The correct answer is

For e: The correct answer is

Explanation:

An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.

When an atom gains electrons, it will form a negative ion known as anion.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

and Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

  • For a:

Halogens are Fluorine (Z = 9), Chlorine (Z = 17), Bromine (Z = 35), Iodine (Z = 53) and Astatine (Z = 85)

Bromine is the 35th element of the periodic table having electronic configuration

This element will gain 1 electron and will form  ion.

The ion formed has 36 electrons.

  • For b:
more :  why is water considered to be abiotic?

Noble gas having 86 protons means the element having atomic number 86 is Radon.

Thus, the correct answer is Radon.

  • For c:

Group 6A elements are Oxygen (Z = 8), Sulfur (Z = 16), Selenium (Z = 34), Tellurium (Z = 52) and Polonium (Z = 84)

Selenium is the 34th element of the periodic table having electronic configuration

This element will gain 2 electrons and will form  ion.

The ion formed has 36 electrons.

  • For d:

Alkali metals are Lithium (Z = 3), Sodium (Z = 11), Potassium (Z = 19), Rubidium (Z = 37), Cesium (Z = 55) and Francium (Z = 87)

Rubidium is the 34th element of the periodic table having electronic configuration

This element will loose 1 electron and will form  ion.

The ion formed has 36 electrons.

  • For e:

Group 4A elements are Carbon (Z = 6), Silicon (Z = 14), Germanium (Z = 32), Tin (Z = 50) and Lead (Z = 82)

Lead is the 82th element of the periodic table having electronic configuration

This element will loose 2 electrons and will form  ion.

The ion formed has 80 electrons.

What is it call when element GAINS electrons?

The atom of this element become an anion.


What is the difference between a nonmetal atom and an anion of the same element?

The anion has more electrons.


Which element will gain three electrons to form an anion?

This chemical element is nitrogen.


How many electrons are in a -2 anion that has 8 protons and 8 neutrons?

Such an anion contains 10 electrons. it is called the oxide ion.


How can you predict if an element will form a cation or an anion?

An element’s number of protons can predict whether it will form a cation or anion. It will form a cation if it has more protons than electrons, or an anion if there are more electrons than protons.


If an element has more electrons then protons what type of ion is it?

Anion.


What is the element group called carbonate?

“Carbonate” is not an element or an element group; instead, it is a polyatomic anion and is one of a large group of oxyanions.


What is an anion and how is it formed?

an anion is simply an atom of an element which has 1 or more excess electrons in addition to its own electrons.this is the reason an anion has negative charge equals to the number of excess electrons it has.



What element has 10 electrons when it form an anion with a 2 negative charge.?

A certain element forms an ion with 10 electrons and a charge of +2. Identify the element

identify the halogen whose anion contains 36 electrons


What kind of element become an anion?

elements that accept electrons become anions


What does a nonmetal element need to do to form an anion?

A non metal must gain one or two electrons to form an anion


What does an element that forms an anion do?

When the element bonds with another element it accepts electrons (it does not give them away) and becomes negatively charged.


Explain how you can tell from an element’s number of valence electrons whether the element is more likely to form a cation or an anion?

anion – nonmetal, wants to gain electrons cation – metal, wants to lose electrons Look metals on the left, others on the right
