According to the periodic table, which statement correctly describes the change from a neutral atom of an element to its ion?

Answers

Answer 1

Answer:

According to the periodic table, a sodium atom forms $Na^+^1$ ion by losing two electrons correctly describes the change from a neutral atom of an element to its ion.

What is a neutral atom?

A neutral atom is an atom where the charges of the electrons and the protons balance.

Atomic number 11.

Mass number 23.

Na Electron arrangement 2, 8 , 1 Will lose 1 electron to gain a full valence shell.

Since now 11 + and 10 –, the overall charge is 1+ So we write $Na^+^1$ or simply $Na^+$ .

The compound NaOH(s) dissolves in water to yield(1) hydroxide ions as the only negative ions
(2) hydroxide ions as the only positive ions
(3) hydronium ions as the only negative ions
(4) hydronium ions as the only positive ions

Answers

Answer: Option (1) is the correct answer.

Explanation:

Sodium hydroxide is a strong base and when it is dissolved in water it completely dissociates into ions.

The chemical equation for this dissociation is as follows.

$NaOH(s) + H_(2)O(l) \rightarrow Na^(+)(aq) + OH^(-)(aq)$

Therefore, we can see that sodium ions are the only positive ions and hydroxide ions are the only negative ions formed upon dissociation of NaOH in water.

Thus, we can conclude that the compound NaOH(s) dissolves in water to yield hydroxide ions as the only negative ions.

What biome could be characterized by large evergreen trees, acidic soil, lichens, and heavy winter snowfall?

Answers

The biome that could be characterized by large evergreen trees, acidic soil, lichens, and heavy winter snowfall is TAIGA. The Taiga experiences extremely cold or hot weather conditions. This is why the main seasons in the taiga are summer and winter. It is actually the largest biome in the world, and is located at the tip of Eurasia up to North America.

Perform the followingmathematical operation, and
report the answer to the
appropriate number of
significant figures.
1204.2 +4.79613 = [ ? ]

Answers

This problem is providing a mathematical expression which the result should be expressed with the correct significant figures. At the end, the result is 1209.0 because of the following:

Significant figures:

In science, the use of significant figures is crucial as long numbers are not necessarily required when reporting a numerical value, for that reason the importance of reporting measurements with the correct number of significant figures.

In the case of additions, we perform the normal operation as the first step:

1204.2 +4.79613 = 1208.99613

Next, we round the result to the leastnumber of decimal places, in this case one because 1204.2 has just one decimal place, unlike the 4.79613 which has five, so that we round the 8 up to 9 and leave a 0 as the onlydecimalplace:

1209.0
