Periodic Table

The element found in group 13 and period 6 of the modern periodic table is Thallium (Tl). It is a soft, malleable metal with some properties of both metals and nonmetals. Thallium is toxic and can be found in trace amounts in certain minerals and ores.

According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.

Phosphorus has 5 electrons in the the third shell.

For periods above period 1, each complete outer shell will contain 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full outer shell with 8 electrons.

Groups 14 and 15 on the Periodic Table feature elements which are metals, non-metals, and metalloids.

Einsteinium, Lawrencium, and Californium are three elements that were named after the same place.

In my reference RB87 is stable, or has a half life of at least 4.9x1010 years.

The symbols of the nonmetals are as follows:

Hydrogen: H

Helium: He

Carbon: C

Nitrogen: N

Oxygen: O

Fluorine: F

Neon: Ne

Phosphorus: P

Sulfur: S

Chlorine: Cl

Argon: Ar

Selenium: Se

Bromine: Br

Xenon: Xe

Iodine: I

Krypton: Kr

Astatine: At

Radon: Rn

It really depends on which acid you want to make since an acid is basically any chemical compound mixed with water to create a PH lower than 7.

Phosphoric Acid (H3PO4) is comprised of Hydrogen, Oxygen and Phosphorus.

Hydrochloric Acid (HCl) is comprised of Hydrogen and Chlorine.

There are far too many different acid types to go into, but there are lots of resources on the Internet for whichever particular one you are looking for.

A bedside table is a small table typically placed next to a bed to hold items such as a lamp, alarm clock, books, or personal items within easy reach of someone while they are in bed. It provides a convenient surface for items that might be needed during the night or first thing in the morning.

It is hydrogen. This element is the only one in its group because it is extremely unique and shares none of the properties of other gases.

The physical properties of any element is defined by two factors, pressure and temperature. All natural pure elements found on earth can exist in all phases. To change the phase (liquid, solid, gas) you can change either the pressure or temperature. The phase indicated on the periodic table is the element's ground state at 1 ATM (a unit of pressure) and 20oC or 293 K (Kelvin, where 0k= absolute zero, when all molecules stop moving).

Chlorine would be most similar to fluorine. They are in the same group of the periodic table, so they undergo the same types of reaction in general, and chlorine is the next most reactive after fluorine.

Astatine is typically described as having a dark purple or black color in its solid state. However, due to its extreme rarity and radioactivity, it is rarely seen in its pure form.

Assuming pure calcium carbide:

CaC2 + 2 H2O → C2H2 + Ca(OH)2

Molar mass of CaC2 = 64.1

Molar mass of water =18

∴ no mol of CaC2 = 492/64.1=7.68mol

∴ no mol H2O =2*7.68=15.35mol

∴mass H2O = 15.35*18 = 276.3g of water

Iron is more reactive than copper, so it can displace copper from copper sulfate in a single displacement reaction. This occurs because iron has a higher tendency to lose electrons and form positive ions compared to copper.

The periodic table contain neutral atoms not a list of cations; most metals are to right.
A cation is an atom who lost electrons.

Modern periodic table has 7 periods and 18 groups.

Silicon is the semi metal that both computer parts and sand have. It is a key component in computer chips and is the second most abundant element in Earth's crust found in sand.

Group I (alkali metals) and Group II (alkaline earth metals) elements on the periodic table are more likely to give away electrons to form positive ions. These elements have one or two electrons in their outermost energy level, making it easier for them to lose these electrons and achieve a stable electron configuration.

1 = Alkali Metals

2= Alkaline Earth Metals

3-12= Transition Metals (Except for elements 58-71 and 90-103)

Poor Metals are below the staircase(the area where the metalloids are, around rows 13-17).

Lead is very heavy, but it is not as valuable or desirable as gold.

The column you're looking for is called the Alkali metals. They are very reactive, but not JUST with water. They actually violently react with almost ANYTHING if they aren't already with another element. Exposure to air, skin, dirt, other metals, It all ends with violence (i.e. huge explosions).
