Metal and Alloys

Metals are elements that are good conductors of electricity. An alloy is a metal made up of more than one element. Combining a metal with another metal or non-metal (alloying) can often improve the material's strength.

Which is in the same period as the element Potassium?

User Avatar

Asked by Wiki User

Two elements, anything in the same column as it, so how about, lithium, and sodium? I'm pretty sure. Lithium and sodium have similar chemical properties to potassium as they are in the same group of the periodic table. They are in group one of the periodic table and are known as the 'alkali metals'. Nearly all elements that are in the same group have similar chemical properties.

Common characteristics of alkali metals include:

Soft/low density metals

React readily with oxygen and water

They will react with water to form an alkaline solution and give off hydrogen gas

Where do you get sodium carbonate?

User Avatar

Asked by Wiki User

Go to Home Depot in the spa section, look for PH increaser, ingredients say 100% sodium carbonate, foot soaking salts also have it but lots of other stuff too which you don't want. costs about 6$ for 16oz

What is the balanced chemical equation for zinc plus acetic acid?

User Avatar

Asked by Wiki User

Zinc hydroxide is (almost) insoluble in water, while caesium acetate is soluble

Zn(CH₃COO)₂(aq) + 2 CsOH(aq) → Zn(OH)₂(s)↓ + 2 Cs(CH₃COO)

The net ionic equation is:

Zn2+(aq) + 2OH-(aq) --> Zn(OH)2(s)

Do alloys rust faster than pure elements?

User Avatar

Asked by Wiki User

Only IRON Rusts. Alloys that contain iron may rust.

Other alloys do not RUST. They may oxidise.

Stainless Steel which is an alloy of iron,.nickel and chrome does not rust. , hence its name Stainless Steel.

What is the appoximate total number of atoms 1.0 mole of lithium?

User Avatar

Asked by Wiki User

Remember the Avogadro Number. This is the number of atoms in an element or the number of molecules in a compound. for an amount of 1 mole.

So 1 mole(Li) it is 6.022 x 10^(23) atoms .

In Numbers

602,200,000,000,000,000,000,000

The ion of aluminium is 'three plus' Symbollically 'Al^(3+)'.

Ships float submarines sink?

User Avatar

Asked by Wiki User

Wrong!!!!

Ships float, and submarines also float.

However, submarines have special buoyancy tanks, which are filled with sea-water, which then makes then sink. The air in these tanks is removed by a vacuum, out into compressed air cylinders. , this allows water to enter and hence the submarine sinks. To make the submarine re-surface, the compressed air in the compression tanks is blown back into the buoyancy tanks, thereby pushing out the sea-water, hence the submarine re-surfaces(floats).

Remember the Archimedian Principle.

'The weight of a body immersed in a fluid is equal to the weight of the fluid displaced'.

As an experiment to yourself, obtain a spring balance, an house brick and a tanks of water.

Attach the brick to the spring balance, with a piece of string, and note the weight in air. Now keeping the brick attached to the spring balance lower it into the water of the water tank, and note the new less weight. The difference in the weight is the weight of the water displaced by the brick.

Hence Archimedes principle and the reason why ships and submarines can float, because the displace less water.

Witch metal does rust the fastest iron bronze?

User Avatar

Asked by Wiki User

First of all to correcty your English . The sentence should start as 'Which'. 'Witch' is a female sorceress.

When asking a question it is 'Which'.

To answer you question.

Only iron RUSTS. No other metal rusts, but oxidises.

So iron rusts and bronze does neither rust nor oxidise.

It comes from the Persian ' Zargun' meaning 'gold like'.

Which is denser sodium or zinc?

User Avatar

Asked by Wiki User

Zinc is denser, because a pellet of it will sink in water.

Sodium is not as dense as water, because it floats on thre surface ], when reacting with water.

What kind of bond is lithium and Oxygen?

User Avatar

Asked by Wiki User

Li2S, which is classified by the AX2 bond type. This bond type is indicative of a linear structure with 180 degree bond angles. This bond is also considered an ionic bond, forcing Lithium to become 2+ and Sulfur to be 2-.

Is potassium hydroxide contains potassium oxygen and helium?

User Avatar

Asked by Wiki User

NO!!!

Potassium hydroxide contains;-

1 X potassium(K)

1 x Oxygen (O)

1 x Hydrogen (H).

To give the formula 'KOH'.

NB Helium is 'He'. It is the most unreactive element of all. It remains in the monatomic gaseous state. So it is not part of potassium hydroxide.

What are the two basic ways in which ions form from an atom?

User Avatar

Asked by Wiki User

An ion can be formed by either losing or ganing electron(s).

E.g.

Sodium metal can become the sodium ion by losing one electron .

Na)g) = Na^+(g) + e^-

Oxygen gas can become the oxide ion by gaining two electrons.

O2(g) + 4e^- = 2O^2-(g).

NB

Uncharged entities are ATOMS .

Charged Entities are IONS.

The word 'ion', is a collective noun for ; - CATIONS ( positively Charged ions), and ANIONS (negatively Charged ions).

Does calcium form a cation or a anion?

User Avatar

Asked by Wiki User

The atomic number of calcium is 20 and its electronic configuration is 2,8,8,2. Calcium atom tends to lose the 2 valence electrons and becomes positively charged calcium ion. Positively charged ions get attracted towards the cathode i.e. the negative terminal in an electric cell. Hence, positively charged ions are known as cations. Calcium is a cation.
