What is the ATOMIC NUMBER for an element with 5 protons, 6 neutrons and 2 electrons?

Chemistry
1 answer:
Ronch [10]1 year ago
8 0

The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) =  5

<h3>What in an atomic number?</h3>

the number assigned to a chemical element according to its atomic number in the periodic system, which places the elements in ascending order of the number of protons in their nuclei. As a result, the atomic number is also the number of protons, which in a neutral atom is always equal to the amount of electrons.

<h3>Briefing:</h3>

Protons and neutrons are added to determine an element's mass number. The only number that may change while maintaining the identity of an element is the number of neutrons for that element (because the atomic number is the number of protons).

Mass number = protons + neutrons

<h3>According to the given data;</h3>

Given:

5 protons,

6 neutrons

2 electrons

Atomic number = ?

We know that the Mass number = protons + neutrons:

Mass number = protons + neutrons

Mass number = 5 + 6:

Mass number = 11

The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) =  5.

Compare the volume of 14.1 g of helium to 14.1 g of argon gas (under identical conditions).
s2008m [1.1K]
The Volumes can be calculated from Masses by using following Formula,

                                        Density  =  Mass / Volume
Solving for Volume,
                                        Volume  =  Mass / Density

Mass of Both Gases  =  14.1 g

Density of Argon at S.T.P  =  1.784 g/L

Density of Helium at S.T.P  =  0.179 g/L

For Argon:
                                        Volume  =  14.1 g / 1.784 g/L

                                        Volume  =  7.90 L

For Helium:
                                        Volume  =  14.1 g / 0.179 g/L

                                        Volume  =  78.77 L

Assume a density of water of 1.00 g/mL, and calculate the mass of water in the solution
tiny-mole [99]

Answer:

1g or 10^-3kg

Explanation:

as you know , the density =mass \volume

so  you have the mass from the number it self

<h2>\frac{1g}{1 ml} so from this equation, you will get 1 g and you can to SI to be 10^{-3}kg</h2>
