The periodic table is a systematic arrangement of the elements. They are arranged according to their atomic number, the number of protons (which in the case of atoms is also the number of electrons) of each atom.
Answer: sorry for the late answer, I just took the test today.
It provides instructions for processes of the cells
Explanation:
Answer:
0.895 g/mL
Explanation:
Step 1: Given data
Mass of liquid Z (m): 2.763 lb
Volume of liquid Z (V): 5.93 cups
Step 2: Convert "m" to grams
We will use the relationship 1 lb = 453.59 g.
Step 3: Convert "V" to milliliters
We will use the relationship 1 cup = 236.59 mL.
Step 4: Calculate the density of the liquid Z
The density (ρ) of the liquid Z is equal to its mass divided by its volume.
Answer:
A. Ionic—Magnesium will give 2 electrons to oxygen, and both will become ions.
Explanation:
An ionic bond will form between the ions of both atoms. Ionic bonds forms when there is transfer of electrons between two atoms so as to achieve a noble configuration.
In the given problem, magnesium is a metal and highly electropositive. This implies that it will readily donate its valence electrons. Oxygen on the other hand is highly electronegative, to complete its outer shell configuration, it requires just two more electrons.
The transfer of the two electrons to the oxygen atom sets up an electrostatic force of attraction between the two ions and an ionic bond results.
