= 1,923

Answer:

The number of valence electrons increases from left to right.

Explanation: The number of valence electrons increases going across a period, or row in the periodic table, for example, group 1 elements have 1 valence electrons and group 2 elements have have 2.

Answer:

Chemical bonds form when the valence electrons of one atom interact with the valence electrons of another atom

Explanation:

They can have different neutron numbers, not proton numbers. If they were to have different proton numbers it would be classified as a different element.

Answer:

That would be a community.

Explanation:

A field of many different species of wildflowers is considered to be a community.

It is called biological community meaning an interacting  group of various species sharing a common location.Factors which determine overall structure of community  are number of species, abundance of each species,interaction among the species and community's ability to return to normal after a natural calamity.

Change of communities over a period of  time is called as ecological succession.Each species in a community has its own characteristic niche . The niche includes all the interactions of the species with other members of the community.An ecosystem comprises of biological community together with its physical environment.

Well, SCl2 is known, so is disulfur dichloride… Cl−S−S−Cl …and BOTH these species are molecular… On the other hand, lithium chloride, an ionic salt, is decidedly non-molecular, and consists of an infinite array of lithium and chloride ions held together by strong electrostatic forces ….. and thus we would expect the salt to have the much higher melting point….

Answer:

The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s

2

It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.

Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s

2

will lose the two 7s electrons to form the cation with +2 charge.

Answer:

Electrons are transferred between atoms together in the ionic compound. The ions are arranged in a regular repeating pattern in an ionic crystal

Explanation:

Ions electrostatically attracts its counter ions and forms the ionic bond between these ions. The structure of ionic compounds depends on the number of atoms and bonded pair of electrons.

Ionic bonds are formed between metals and non-metals. Metals are electron rich and easily loss one or more electrons to the electron deficient non metals.

The loss of electrons make the atom forms a positive ion called cations. The gain of electrons make the formation of anions or negative ions. These positive ions and negative ions attracts electrostatically and forms ionic bond between them.

The structure of ionic compounds depends on the number of bonded atoms, size, presence of lone pairs etc. In solution ionic compounds exists as separate ions.

Answer:

An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy

Answer:

Potassium Hydroxide Solution =

or

Potassium Hydroxide =

Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.

As it is in the question, we can map the reactants and product:

Reactants                   Product

Ammonium                 Ammonia

Sulfate                         Sulfate

________                   Potassium

________                    Water

Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.

This becomes clear when we consider the net ionic equation:

Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water

if we write this a balanced chemical equation:

(NH₄)₂SO₄   +  2KOH  →  K₂SO₄ + 2NH₃ + 2H₂O

if we write the reaction as an ionic equation

2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O

if we remove the ions that appear on both the reactant and product side (spectator ions)
