Answer:

1). Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.

2) In contrast, the number of neutrons for a given element can vary. Forms of the same atom that differ only in their number of neutrons are called isotopes.

3) Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

The balanced dissociation equation for Cs₂CO₃ is:

Cs₂CO₃(aq) —> Cs⁺(aq) + CO₃²¯(aq)

A dissociation equation is an equation showing the available ions present in a solution.

To obtain the dissociation equation, the compound must be dissolved in water to produce an aqueous solution.

The dissociation equation for Cs₂CO₃ can be written as follow

Cs₂CO₃(aq) —> Cs⁺(aq) + CO₃²¯(aq)

Answer:

there are a total of nine orbitals in a third energy level

Explanation:

Answer:

d. 10

Explanation:

The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12

Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.

The confusing thing is that + means subtract and - means add here.

The mole fraction of methanol in the mixture is 0.444

We'll begin by calculating the number of mole of water.

Mole = mass / molar mass

Mole of water = 45 / 18

Mole of water = 2.5 moles

Finally, we shall determine the mole fraction of methanol.

Mole fraction of methanol =?

Mole fraction = mole / total mole

Mole fraction of methanol = 2 / 4.5

Mole fraction of methanol = 0.444

Thus, the mole fraction of methanol is 0.444

Answer:

Periodicity is caused by regular and predictable variations in element atomic structure. ... The rows in the periodic table (the periods) reflect the filling of electrons shells around the nucleus, so when a new row begins, the elements stack on top of each other with similar please help me rank up

Periodicity means the repeating trends in properties of elements in a regular interval.  Precocity in chemical properties depends on the atomic structure because, the size, number of electrons, etc affects their reactivity.

Periodicity is the repetition in in trends in properties after a regular interval. In periodic table, all the elements are classified into different groups and periods.

Groups are vertical columns containing elements of same number of valence electrons and similar chemical and physical properties. Periods are horizontal rows where elements are arranges in the increasing order of atomic number.

Along a period the atomic size decreases, ionization energy and electronegativity increases. But down a group just the reverse for this happens.

In a chemical reaction only valence electrons are participating and the size and number of valence electrons etc affects the chemical reactivity of elements. That's why it is said like periodicity in chemical properties is based on the atomic structure.

Answer:

0.2491

Explanation:

1mole of a gas contains 6.02 × 10²³molecules

x moles will contain 3.408 × 10²¹

x = 1 × 3.408 × 10²¹/ 6.02 × 10²³

= 5.66 × 10^-3moles

Mole = mass/ molar mass

mass = Mole × molar mass

= 5.66 × 10^-3 × 44.01

= 249.0966 × 10^-3

= 0.2490966

to 4 decimal places = 0.2491

Answer:

C2Br6

because bromine is a liquid volatile

According to the forces of attraction and boiling point C₂Br₆ is most volatile as its boiling point is very low.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.
