Answer: It’s Nh !!!
Explanation:
Alkali metals and alkaline earth metals always produce cations, while halogens always produce anions. so, option A is correct.
What is cation ?A cation has a net positive charge because it contains more protons than electrons. One or more electrons must be lost in order for a cation to develop normally, these electrons are drawn away by atoms having a larger attraction for them.
Main-group elements often produce cations with a charge equal to the group number as they move from the extreme left to the right on the periodic table. To put it another way, group 1 elements produce 1+ ions, group 2 elements produce 2+ ions, and so on.
Cations, which have a positive charge, are created when electrons are lost. Anions, which have a negative charge, are created when electrons gain energy.
Thus, option A is correct.

Indicate whether each statement is true or false: a. Substitutional alloys tend to be more ductile than interstitial alloys. b. Interstitial alloys tend to form between elements with similar ionic radii. c. Nonmetallic elements are never found in alloys.
Answer:
Substitutional alloys tend to be more ductile than interstitial alloys. true
Interstitial alloys tend to form between elements with similar ionic radii.false
Nonmetallic elements are never found in alloys. false
Explanation:
Substitutional alloys consists components having similar atomic(ionic) radii as well as common bonding characteristics. In interstitial alloys, atoms in interstitial positions must have a much smaller covalent radius than the solvent atoms. Interstitial atoms are generally less ductile than substitutional alloys.
Nonmetals are found in alloys. For instance, carbon is a component of the common alloy called steel.
___are organelles found in plant cells. They absorb energy from sunlight and use that energy to drive chemical reactions that produce sugars and oxygen.

how dose the scientist know the substances goes through a change of state during the time period labeled B on the graph?
Answer:
The temperature remains constant
Explanation:
In a plot of temperature against time, it is easy to spot the points on the graph where a change of state is taking place.
During a change of state, the temperature does not not change with time. These are points that are plateaus on the temperature-time graph.
This is because, during phase change, the heat that is added is used in breaking intermolecular forces therefore a temperature change is not observed until the phase change is complete.

Explanation:
For the elements in the "f-block," how is the row number related to the principal energy level for the last orbital notation of their electron configurations?"
Answer:
See explanation
Explanation:
Given that the row number is the same as the period or energy level(shell) in which the electron is found.
If we designate this row number as "n", we know that the highest principal energy level for the f orbitals is obtained as (n-2) f.
Thus, we obtain the highest principal energy levels for the "f block" elements by subtracting 2 from the row number.

What happens to the pH of an acid when the solution is diluted by a factor of 10?
Answer:
Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic.
Explanation:
However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is not alkaline.

Which element’s atoms have the greatest average number of neutrons?
Answer:
53
Explanation:
the atomic number is 53, then Number of neutrons=127-53=74 Since, the number of neutrons are large in Tellurium, therefore Tellurium have the greatest average number of neutrons.
