Answer:

Anion ( F^-)

Explanation:

An anion is formed when a non metal receives an electron from metallic atom.

Fluorine atom has electronic configuration of 1S2 2S2 2P5. It therefore needs 1 electron to attain the noble gas configuration. Thus to do this, fluorine will receive 1 electron from metallic atom to form fluoride ion(F^-) with electronic configuration as 1s2 2s2 2p6 and thus forming ionic bond.

This can be seen when sodium react with fluorine to form sodium fluoride according to the equation

1. Na —> Na+ + e-

2. F + e- —> F-

Combining 1 and 2, we have:

Na + F + e- —> Na+ + F- + e-

Na + F —> Na+F-

The above illustration indicates ionic bonding as electron was transferred from the sodium atom to the fluorine atom, thus forming sodium ion (Na+) and fluorine ion(F-)

Answer:

An anion

Explanation:

An ion of flourine wife form an anion. What is an anion? An anion is a negatively charged atom.It occurs as a result of gain of electron by an atom to stabilize it's octet structure.

This is a common phenomenon for non metals and halogens are a good example of that which are strongly electronegative with electronic configuration of 2,7......

Copper(II) carbonate undergoes thermal decomposition. One of the pro
Llana [10]

Answer: The green copper (II) carbonate (CuCO_3) changes to black copper oxide (CuO)

CuCO_3(s)\stackrel{\Delta }\rightarrow CaO(s)+CO_2(g)

Explanation:

Decomposition is defined as the chemical reaction in which a single compound gives two or more simple substances. It requires energy to break the bonds between reactants, thus is an endothermic process.

Thermal decomposition uses heat for decomposition.

The chemical equation for thermal decomposition of copper (II) carbonate is:

CuCO_3(s)\stackrel{\Delta }\rightarrow CaO(s)+CO_2(g)

The green copper (II) carbonate (CuCO_3) changes to black copper oxide (CuO)

HELP I WILL MARK YOU AS THE BRAINLIEST ANSWER
borishaifa [10]

Hey there! Here is the answer:

B.) decrease; increase

Here's why:

As you move from left to right across a period on the periodic table the size of an atom will decrease. As you move from top to bottom down a group on the periodic table the size of an atom will increase.

I really hope this answer helps you out! :)
