The correct answer is A) They all have similar chemical properties.

Explanation:

In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.

These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".

What is the correct iupac name of CH3-CH2-CH2CHO ?
kow [346]

the correct IUPAC name of the compound is 1-Butanal.

<h3>What are IUPAC names?</h3>

It is a system of naming organic compounds based on the longest carbon-to-carbon single bonds. It does not matter whether these longest chains are continuous or in a ring.

Thus, when the compound with the chemical formula, CH3-CH2-CH2CHO is considered. The longest carbon-to-carbon chain is 4. The 1st carbon carries a functional group known as an aldehyde.

Aldehydes are equipped with the carbonyl group and have the general formula R−CH=O. They are also sometimes referred to as formyl.

Aldehydes are named after their parent alkane chains with a slight modification. The 'e' is replaced with 'al'

The aldehyde in this case has four carbons. This means that the parent alkane is Butane. Therefore, the name of the compound will be 1-Butanal.

What has the lowest ionization erergy?
Svetach [21]

Answer:

Francium (Fr)

Explanation:

From the given choices, francium will have the lowest ionization energy.

Ionization energy is the energy required to remove the most loosely held electron within an atom.

The magnitude of the ionization energy depends on the characteristics of the atom in relation to its nuclear charge, atomic radius, stability etc.

  • Generally on the periodic table, ionization energy increases from left to right on the table
  • As you go from metals to non-metals and to gases, the value of the ionization energy increases steadily.
  • Down the group, the value reduces.
  • Since Francium is the most metallic of all the given choices, it has the highest ionization energy.
