Periodic Table

likely it would form the +2 ion (the mercury), so put the Hg in brackets, with a +2 charge at the top right corner out side the bracket. put a bromine, with 8 electrons, in a bracket, with a -1 charge at its top right outside the bracket, and then do it again. formula has to be HgBr2. if it's the Hg+1 ion, do the same as I just wrote, but only include one bromine ion

Metal is generally not as prone to shattering as materials like glass or ceramic. However, certain types of metal, such as cast iron or hardened steel, can be brittle and more susceptible to shattering under intense impact or stress. Overall, metal is known for its toughness and ability to withstand deformation before breaking.

An excited atom will have electrons that are in higher energy levels than the ground state configuration. This can be observed by seeing electrons in higher energy orbitals or by an electron being promoted to a higher energy level. Spectroscopic techniques can also be used to identify excited atoms.

All of them. There is no problem with elements not having stable electron configurations. The only stability issue concerns the nucleus, not the electrons-- all elements except helium have isotopes with unstable nuclei, some have only unstable nuclei (radioactive elements), and some have only very short-lived unstable nuclei.

Germanium belongs to group IVA or group 14 and period 4

The weight of a football is a non-example of atomic mass. Atomic mass refers to the average mass of an atom of a chemical element, while the weight of a football is a measure of the force of gravity acting on the football due to its mass.

No.

Mg forms positive ions, Mg2+ ions

Elements of the periodic table in their natural state can be found in the Earth's crust, atmosphere, oceans, and even living organisms. Some elements occur in their pure form as minerals, while others are part of compounds or mixtures in nature. Scientists study geological formations, conduct chemical analyses of rocks and minerals, and use methods like spectroscopy to identify elements in their natural state.

Vertical columns in the periodic table indicate elements with similar chemical properties due to having the same number of valence electrons. These elements belong to the same group and exhibit similar reactivity and bonding patterns.

An atomic mass of 12 means carbon, and its atomic number is 6.

The charges of atoms on the periodic table are determined by the number of protons and electrons they have. Protons carry a positive charge (+1) and electrons carry a negative charge (-1). The charge of an atom is balanced by the number of protons, which equals the number of electrons in a neutral atom.

The first twenty elements in order are: Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium, and Calcium.

You cannot form elements on the periodic table of elements. All the elements on this table were already in existence before man ever set foot on the earth. An element is a substance that cannot be broken down into a simpler state, meaning that man could not form one element out of two things, because then it could be broken down into those two separate things once again.

"N" in the periodic table refers to the element nitrogen, which has atomic number 7. Nitrogen is a nonmetal with various important industrial applications, such as in the production of fertilizers and explosives.

Periodic table lists elements and not compounds.

The chemical symbol CO2 represents carbon dioxide, a colorless and odorless gas composed of one carbon atom covalently bonded to two oxygen atoms. It is a greenhouse gas that occurs naturally in the Earth's atmosphere and is produced by various human activities such as burning fossil fuels.

Rhodium is primarily found in platinum group metal ores, such as pentlandite and pyroxenite. It is commonly mined in South Africa, Russia, and Canada. In nature, rhodium is often found alloyed with other platinum group metals like platinum and palladium.

I do not see an isotope of iridium that does alpha decay. There is an interactive link to isotopes below. (Perhaps I am missing it.)

The halogens (group 17) receive one electron per atom when forming ionic bonds. When this occurs, the halogen becomes a negatively charged ion with a charge of 1-.

The allowed orbital types for the second period of the periodic table are s and p orbitals. This means that elements in the second period can have a maximum of 2 electrons in an s orbital and 6 electrons in p orbitals.

The horizontal rows are known as periods.

Because elements in the first row (second period) form multiple bonds much more readily than elements in the second row (third period).

N2 is a gas, with the molecule triple-bonded. But P4 is a solid, with each atom at a corner of a tetrahedron, and single bonds to the other three atoms.

Similarly O2 is a gas with double-bonded molecules, but S8 is a solid with sulfur atoms in 8-membered rings. And most dramatically of all, carbon dioxide is a gas with double-bonded atoms: O=C=O , while silicon dioxide is quartz -- a network structure with only single bonds. Each silicon atom is surrounded by and single-bonded to four oxygen atoms; each oxygen atom is single-bonded to two silicon atoms.

The rule of 8, also known as the octet rule, states that atoms tend to gain, lose, or share electrons in order to have a full outer electron shell with 8 electrons. This stability is similar to the noble gas configuration. Elements will often form ions or bonds to achieve this electron configuration.

The number of protons in an atom is equal to the atomic number of the element. To find the number of electrons, it's also the same as the number of protons in a neutral atom. So for example, oxygen with atomic number 8 has 8 protons and 8 electrons in a neutral atom.

The halogens are under group 17 (column 17) on the periodic table. They are in the column right next to the noble gases. They have the highest electronegativity values and typically exist as either anions or diatomic gases. Examples of these elements are fluorine, chlorine, bromine, and iodine.
