Answer:
d. Mg²⁺
Explanation:
c. K⁺
d. Mg²⁺
Based on the Bohr's atomic model, the atom has electrons (Mass 0; Charge -1), protons (Mass 1; Charge +1) and neutrons (Mass 1; Charge 0).
The atomic number is equal to the number of protons. That means there are 10 protons. As the Neon is netural, the amount of electrons must be 10.
A neutral atom of Mg has 12 electrons, that means the Mg²⁺ has 10 electrons the same than Ne.
Right option is:
d. Mg²⁺SUPER EASY. just check if i'm right or not. WILL GIVE BRAINLIEST

Read the following paragraph from the section "Dreaming Of A World Deep Below."
The interior of our planet has long held a fascination for philosophers and storytellers. Some have speculated that another inhabited world lies beneath our own. In 1864, Jules Verne’s novel "Journey to the Center of the Earth" described the fictional adventures of explorers traveling under our planet’s surface. It was a best-seller. People wondered if the world Verne described below our own could be real.
Why does the author include this paragraph in the article?
Question 9 options:
to show how much scientific progress regarding the Earth's core was made during Lehmann's lifetime
to explain a number of popular theories concerning the composition of the Earth's core
to demonstrate how Lehmann's discovery confirmed what Jules Verne already knew about the Earth's core
to describe the attitudes Lehmann needed to overcome in order to introduce her work to the scientific community
Answer:
B
Explanation:
The interior planet has fascinated a lot of people so a lot of theories have been made about what's in there.
The reason author include this paragraph in the article is to explain a number of popular theories concerning the composition of the Earth's core. Thus, option B is correct.
What is acronym?
Acronym has been defined as the short form of long words such as very important person and the acronym of very important person has been VIP. The word acronym has been used to denote the short term of the word in which two or more than two words combined together to form new short word.

Copperhead snakes can reproduce both sexually and asexually. which option describes a situation where sexual reproduction is more advantageous for the copperhead snake.
A. a new disease develops , so having more genetic variation among there off spring is an advantage.
B. a new type of pray arrives in the environment , so they have more food sources.
C. a short and mild winter makes the environment more livable for them and all the other organisms in the area.
D. they migrate to a new location where prey and shelter are more abundant and easier to find.
Answer:
Answer A:
a new disease develops , so having more genetic variation among there off spring is an advantage.
Not 100% sure but A seems the most likely answer.
Explanation:
The question is asking where sexual reproduction is more of an advantage and I'd say that having more genetic variation would be caused by sexual reproduction and not as much or at all in asexual reproduction.
with B, C, and D. It wouldn't really be an advantage to do one or the other in this context.

7. Calculate the net charge of the following atoms.
Atom A: has 6 protons and 4 electrons
Atom B: has 9 protons and 9 electrons
Atom C: has 10 protons and 14 electrons
Atom D: has 33 protons and 29 electrons
Answer:
any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
Explanation:
Answer:
Atom A: +2 Atom B: 0 Atom C: -4 Atom D: +4
Explanation:
We know that protons have a positive charge and electrons have a negative charge. Therefore, we will treat the electrons as a negative number. The net charge is the sum of electrons and protons.
Atom A = 6 + (-4)
because electrons as negative.
Net charge = +2
Atom B = 9 + (-9)
Net charge = 0, or neutral
Atom C = 10 + (-14)
Net charge = -4
Atom D = 33 + (-29)
Net charge = +4

All alkalis are bases but not all bases are alkalis. True or False?
Answer:
A substance that neutralizes an acid is generally called a base and the basic substances that are soluble in water and alkali and the properties of alkalis are due to these hydroxide ions(OH−). ... - Thus, conclusively it can be said that all alkalis are bases but all bases are not alkali.
Answer:
This is false
Explanation:
it is actually the opposite, all bases don't dissolve in water, but alkali is a base that does dissolve in water. So, alkalis are bases, but not all bases are alkalis
