Periodic Table

Noble Gases: Because Noble Gases are already in a stable form, they are not as likely to bond with other atoms as are those farther from a stable form.

Noble Gases are found in group VIII, which is the far rightmost column.

Te = Terbium.

Lanthanoid

atomic # 65

Mass # 158.92 [Xe] 4f9 6s2

Technetium is the chemical element with atomic number 43 and symbol Tc.

Tb stands for the element Terbium. which has an atomic number of 65, atomic weight of 158.9253, its in the lnthanoids, block f, period 6, has a density of 8.23 g/cm^3. is a solid, and has a boiling point of 3500k, melting point of 1629k, and has a electronegetivity of 1.1

A noble gas, such as helium or neon, is unreactive and has a full outer electron shell on the periodic table. This full outer shell makes them stable and less likely to form chemical bonds with other elements.

1-Atomic size = decreases

2-Ioniztion energy = increases

3-Electronegativity = increases (except Argon)

4-Metallic character = decreases

5-Melting point = first increases then decreases

The atomic number of sodium is 11. Other numbers are 3rd period and column 1.

The color of an element on a periodic table does not provide information about its properties at room temperature. The color usually represents the state of the element in its most stable form or as it appears in nature; for example, gases are often depicted in blue, metals in grey, and nonmetals in various colors.

it is carbon and 2 oxygen atoms

a.k.a carbon dioxide

EU stands for Europium on the periodic table. It is a rare earth element that is commonly used in the production of phosphors for electronic devices such as TVs and computer screens. Its atomic number is 63.

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. They are determined based on their atomic mass, which is the sum of protons and neutrons in the nucleus. Isotopes of an element have similar chemical properties but may have different physical properties, such as radioactive decay rates.

Copper sulfate would crystalize as blue crystals, water would evaporate.

To get the copper sulfate itself to evaporate you would need to heat it, melting the dry crystals then vaporizing them.

Moving left or right typically refers to shifting one's position or direction in a lateral manner, either physically or in a metaphorical sense. It can indicate a change in perspective, decision, or course of action.

The noble gases have a full outer electron shell, making them very stable and unreactive. This is because they already have a complete set of electrons, so they do not need to gain, lose, or share electrons with other elements to achieve stability.

Thermal stability decreases down the group due to the increase in atomic size and metallic character. Larger atoms have weaker metallic bonds, leading to decreased thermal stability as we move down the group. Additionally, the presence of higher energy levels and more electron shielding diminishes the attraction between the nucleus and outer electrons, making the elements less stable at higher temperatures.

Hydrogen wants to obtain one electron to achieve a stable electron configuration similar to the noble gas helium.

No, sulfur has a higher electron affinity than oxygen. Electron affinity is the energy released when an atom gains an electron to form a negative ion, and sulfur's larger size and higher effective nuclear charge make it more likely to attract an additional electron compared to oxygen.

It is metal as it conducts electricity and it is on the left side of that big black line in the periodic table. It is in fact used in wires for it's conductive properties.

All metals react with other elements by losing their outermost electrons in their atoms forming 'positive ions'. So the ease with which they can lose these electrons gives us an indication of how reactive they are.

Aluminium, as an example has three electrons in the outer orbits of each aluminum atom, and so three have to be lost for the aluminum to react. Calcium, a more reactive metal has only 2 electrons in the outermost orbits of its atoms, and so these are more easily lost, making calcium more reactive.

However all group 1 elements (Lithium, Sodium, Potassium, Rubidium, Caesium, Francium) all have just one electron in the outermost orbits of their atoms, and so they are the most reactive of all metals as this one electron is very easily lost.

More than this, the reactivity gets stronger as the atoms get larger (as you proceed down the group) because the outermost electron is further away from the nucleus and is therefore less strongly bound to the atom than the outermost electron in smaller atoms like lithium as the electron is closer to the nucleus and more tightly bonded to the rest of the atom.

This means that Lithium is the least reactive of the Group 1 elements and Francium the most reactive. Francium is radioactive and does not exist in large quantities, so practically caesium is the most reactive. Lithium, when placed on the surface of some water fizzes vigorously. However, caesium, when placed in a glass trough of water explodes violently, with enough force to shatter the trough and possibly damage greatly the surrounding area too.

Metalloids are located on the periodic table along the staircase dividing metals to the left and non-metals to the right. They include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids have properties intermediate between metals and non-metals.

the chemical symbol for iron is Fe. the atomic number is 26

Uranium belongs to the actinide series in the periodic table, and shares similar chemical properties with other actinide elements such as thorium and plutonium. These elements all have similar electron configurations and reactivity due to the presence of the same number of valence electrons.

sodium(Na) belongs to the Ist group. This group is also known as alkaline metals.
