Principal (shell) quantum number - n

Describes the energy level in the atom (1 through 7)The maximum number of electrons in n is 2n2 
2. Angular (subshell) quantum number - l
Describes the sublevel in nEach energy level has n sublevels 
3. Magnetic quantum number - m
Describes the orbital within ls has 1 orbitalp has 3 orbitalsd has 5 orbitalsf has 7 orbitals 
4. Spin quantum number - s
Describes the spin of the electrons in an orbital.Electrons in the same orbital must have oppisite spins.Possible spins are clockwise or counterclockwise.

Identify the blocks and groups of elements in the periodic table

djyliett [7]

Explanation:

The periodic table is a table that arranges elements based on their atomic numbers into groups and periods.

The groups are the vertical arrangement of elements. All elements in a group share similar chemical properties because they have the same number of elements in their valence shell. The periodic table groups are:

Group Other names

1A or 1 Alkali metals

IIA or 2 Alkaline earth metals

IIIA or 3 Boron family

VIA or 6 Chalcogens

VIIA or 17 Halogens

O-18 Inert elements

IIIB-IIB Transition elements

There are 18 vertical columns divided into 8 tall groups or main groups which are 1A to O. The short groups or subgroups are from numerals 1B to VIII.

The periodic table can be divided into four blocks based on the type of sublevels their valence electrons occupy.

Group IA and IIA constitute the s-block
Group IIIA to O constitute the p-block
The transition elements makes up the d-block
The lanthanides and actinides makes up the f-block

10 In a bond between an atom of carbon and an atom of fluorine, the fluorine atom has a

Oksanka [162]

The best answer is (2) stronger attraction for electrons, for the fluorine atom has a higher electronegativity than the carbon one, if not highest of all nonmetals.

An unknown metal cylinder has a mass of 34.3 g and a volume of 2.1 mL . What is the density of the metal in g / m * L ?

saul85 [17]

Taking into account the definition of density, the density of the metal is 16.33 $\frac{g}{mL}$ .

<h3>Definition of density</h3>

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Density of the metal in this case</h3>

In this case, you know that:
