Which statement is true concerning the elements in families 1 and 2?
jeka57 [31]

Answer:

The correct option is;

D. All the elements in families 1 and 2 can place all their shell electrons in the s sub-level

Explanation:

The elements in families 1 and 2 also called the group 1A and group 2A elements are known as the alkali and alkaline earth metals. The elements in the families 1 and 2 are also referred to as the s-block elements as they have their valence electrons which are 1 and 2 respectively, in the s-orbital or s sub-level

Due to their low ionization energy, and the ease with which they donate their valence electrons, elements of the families 1 and 2 are known to be very reactive, and are found in a combined state in nature.

What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? quzket
Ivanshal [37]

The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Carbon is known as a tetravalent compound.

It has four electrons in its outermost shell. It forms a covalent bond with other compounds.

The number of neutrons. = 6

Number of electrons = 6

Number of protons = 6

So the atomic number of the compound is,

The atomic number of an element = Number of protons present in its nucleus

The number of protons given in the compound is 6.

So the atomic number of the compound is also 6.

Carbon has six atomic numbers.

Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Which of the following groups would be found on an alcohol molecule?
photoshop1234 [79]

<span>I’ve answered this question before so if these are the choices to the question presented:

An oxygen atom double-bonded to a carbon atom, with a hydrogen atom single-bonded to the same carbon atom. </span><span>

<span>A hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain. </span>

<span>A carbon atom single-bonded between two other carbon atoms, with an oxygen atom double-bonded to the central carbon atom as well. </span>

<span>An oxygen atom single-bonded between two carbon atoms within a carbon chain. 


Then, the answer would be “a hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain.<span>”</span></span></span>
