MgF2

Question: Combine and name the compound:Example:Mg2+ and F- =MgF2 is magnesium fluorideNa+ andC2H3O2Ni2 andCrO42-K+ and OH-Fe3+ andN3-Al3+ andF-Co2+ and No2-Fe3+ and O2-Thanks.

Hence, two fluorine atoms will chemically combine with one atom of magnesium to acquire stability. Therefore, magnesium will donate its valence electron to each fluorine atom. This will form an ionic compound magnesium fluoride ( ).

Magnesium fluoride

barium cation

Magnesium oxide has the formula MgO which is one Mg2+ ion to one O2− ion.

Cs

NaCl

Sodium has a positive 1 charge and chloride has a negative 1 charge. Thus one sodium cation cancels one chloride anion resulting in the formula Na1Cl1 or NaCl. This formula is called the “formula unit” since it represents only one unit of the vast NaCl array or lattice.

Fluoride

Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero.

Iron is an element with atomic symbol Fe, atomic number 26, and atomic weight 55.85.

Cation, atom or group of atoms that bears a positive electric charge. See ion. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition…

If an atom, or atoms, has a balanced number of electrons (negative charge) and protons (positive charge) they are neutral overall….Cation vs anion chart.

A cation (+) (/ˈkætˌaɪ.ən/ KAT-eye-ən, from the Greek word κάτω (káto), meaning “down”) is an ion with fewer electrons than protons, giving it a positive charge. There are additional names used for ions with multiple charges.

There are specialized types of ions. Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule.

If K+ can cross via channels, it will begin to move down its concentration gradient and out of the cell. The movement of K+ ions down their concentration gradient creates a charge imbalance across the membrane.

Answer: Atomic number of k = 19, We see that, Pottasium(k) has 1 electron in it’s outermost shell, So k+ will have, 8 outermost electrons, According to Octet rule, K+ will be more stable !.

The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali.

Symptoms of high potassium

• tiredness or weakness.
• a feeling of numbness or tingling.
• nausea or vomiting.
• trouble breathing.
• chest pain.
• palpitations or irregular heartbeats.

This may include:

1. Water pills (diuretics) help rid your body of extra potassium. They work by making your kidney create more urine. Potassium is normally removed through urine.
2. Potassium binders often come in the form of a powder. They are mixed with a small amount of water and taken with food.
