negative ions form when atoms _______ valence electrons.
Answers
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

What is patagium and what do you meant by prehensile tail
Answers
The patagium (plural: patagia) is a membranous structure that assists an animal in gliding or flight. The structure is found in living and extinct groups of animals including bats, birds, some dromaeosaurs, pterosaurs, gliding mammals, some flying lizards, and flying frogs.
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees.
Answer:
patagium in American English
1. a wing membrane, as of a bat. 2. the extensible fold of skin of certain insects or of a gliding mammal or reptile, as a flying squirrel.
Explanation:
A prehensile tail pertains to the tail of certain animals that enable the latter to grasp or hold objects. ... A fully prehensile tail is one in which the animal can fully hold on to and manipulate an object with its tail.

(i)C has 10 protons and 12 neutrons so a mass of 10 +12 =22
element 10 is Neon (Ne) so this isotope is Ne-22
(ii) they all have the sane atomic number so the same number of electrons
with an electronic structure of 1s2s22p6
(iii) A weighs 20, B weighs 21, C weighs 22
the ratio is 1:2:3
weighted average weight is therefor
(1X20 +2X21 +3X22)/6 =21.3

Do the boiling points and melting points of these elements support the claim that elements of the same group have similar physical characteristics?
Answers
Answer:
Elements in the same group has different physical properties such as boiling and melting points. However there are trends of their physical properties down the group.
Explanation:
You should look at the perdoic table to for extra help
The boiling points and melting points of the given elements does not support the claim that elements of the same group have similar physical properties.
What are boiling point and melting point?The boiling point of a substance is the temperature at which it changes from liquid state to gaseous state. Melting point is the temperature at which the substance changes from solid to liquid state.
Elements in the same group shows similar physical and chemical properties. But from the boiling and melting point we cant say that they are in the same group.
Elements in a group shows a trend in boiling point and melting point but cannot be distinguished with this from other groups.
Hence, boiling point and melting point of the elements do no support for the similar properties in a group.

Answer:
more than one kind of atom. a solution of atoms and molecules.
Explanation:
a compound always contains more than one type of atom.
Although the formula for sodium chloride is NaCl, the compound does not contain actual NaCl molecules. Rather, it contains equal numbers of sodium ions with a charge of positive one (Na+) and chloride ions with a charge of negative one (Cl−).
An electrochemical cell was designed using magnesium anode and zinc cathode calculate the EMF of the cell
Will the reaction be spontaneous or not? Give reason for your answer
Answers
When the cell potential is positive then the electrochemical reaction is spontaneous. The Ecell is positive when Zn serves as cathode and Mg serves as anode hence the reaction is spontaneous.
An electrochemical cell is any type of cell in which energy is produced by a spontaneous chemical reaction. Redox reactions that occur in an electrochemical cell produce energy.
An electrochemical cell becomes spontaneous only when Ecell is positive. Ecell is positive when a metal that has a more negative electrode potential serves as the anode.
Since Mg has a more negative electrode potential that Zn, it follows that a cell in which Mg is the anode and Zn is the cathode will have a positive Ecell and the reaction will be spontaneous.

15.24. Calcium hydroxide, also known as slaked lime, is used in industrial processes in which low concentrations of base are required. Only 0.16 g of Ca(OH)2 dissolves in 100 mL of water at 25°C. What is the concentration of hydroxide ions in 250 mL of a solution containing the maximum amount of dissolved calcium hydroxide?
Answers
The concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M
We'll begin by calculating the number of mole of in 0.16 g of Ca(OH)₂. This can be obtained as follow:
Mass of Ca(OH)₂ = 0.16 g
Molar mass of Ca(OH)₂ = 40 + 2[16 + 1] = 74 g/mol
Mole of Ca(OH)₂ =?Mole = mass / molar mass
Mole of Ca(OH)₂ = 0.16 / 74
Mole of Ca(OH)₂ = 0.00216 mole Next, we shall determine the molarity of the stock solution of Ca(OH)₂.Mole of Ca(OH)₂ = 0.00216 mole
Volume = 100 mL = 100 / 1000 = 0.1 L
Molarity of Ca(OH)₂ =?Molarity = mole / Volume
Molarity of Ca(OH)₂ = 0.00216 / 0.1
Molarity of Ca(OH)₂ = 0.0216 MNext, we shall determine the molarity of the diluted solution. This can be obtained as follow:Volume of stock solution (V₁) = 100 mL
Molarity of stock solution (M₁) = 0.0216 M
Volume of diluted solution (V₂) = 250 mL
Molarity of diluted solution (M₂) =?M₁V₁ = M₂V₂0.0216 × 100 = M₂ × 250
2.16 = M₂ × 250
Divide both side by 250
M₂ = 2.16 / 250
M₂ = 0.00864 MThus, the molarity of the diluted solution is 0.00864 M
Finally, we shall determine the concentration of the hydroxide ions, OH¯ in the diluted solution. This can be obtained as follow:Ca(OH)₂(aq) —> Ca²⁺(aq) + 2OH¯(aq)
From the balanced equation above,
1 mole of Ca(OH)₂ contains 2 moles of OH¯
Therefore,
0.00864 M Ca(OH)₂ will contain = 2 × 0.00864 = 0.01728 M OH¯
Thus, the concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M
