Provide your answer in the following format: [element name], [chemical family]

Answers

Answer 1

Answer: Bismuth (Bi) , Nitrogen family

Explanation:

As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.

Now as the electrons are filled according to afbau's rule , the electronic configuration of the element will be :

[tex][Xe]4f^{14}5d^{10}6s^26p^3[/tex]

Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is a p block element. It lies in group 15 which is nitrogen family.

Which is the correct Lewis dot structure for BeH2 ?

Answers

H• •Be• •H --> H:Be:H
Since there are 4 valence electrons in total, Beryllium has 2 and Hydrogen has 2. You would put the Be in the middle because there is only 1 of them.

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H

What does the Lewis dot structure show?

The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.

The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

Explain why the electron configuration of 2-3-1 represents an atom in an excited state?

Answers

Answer:

See explanation

Explanation:

If we look at the electron configuration closely, we will discover that the element must have had a ground state electron configuration of 2,4.

This is because, the innermost shell usually holds two electrons while the outer shells hold eight electrons each. The four electrons must be accommodated in the second shell in the ground state configuration of the compound.

However, when the atom is excited, one electron from this shell may move to the third shell to give the excited state configuration 2-3-1 as shown in the question.

If you have 2.0 moles of sodium chloride (NaCl), what is its mass in grams?

Answers

Answer:

117g

Explanation:

Given parameters:

Number of moles = 2moles

Unknown:

Mass of NaCl = ?

Solution:

To solve the problem, we need to use the expression below;

Mass of NaCl = number of moles x molar mass

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

So;

Insert the parameters and solve;

Mass of NaCl = 2 x 58.5 = 117g

Given a balanced chemical equation it is always possible to determine
A)
the physical state of the products and reactants
B)
whether a reaction will or will not take place
C)
the relative number of moles taking part in the reaction
D)
the conditions necessary for the reaction to take place

Answers

Answer:

C) the relative number of moles taking part in the reaction

Explanation:

From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.

The number of moles is the amount of the reacting specie that makes up a chemical reaction.

In balanced chemical equation, the number of moles of reactants and products must be the same. From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.

how to find the electron in an atom/element

Answers

Answer:

to find the number of electrons an element has locate it on the periodic table of elements find the atomic number and note the number of protons because they are naturally electrically neutral

Answer:

M-A=N

Explanation:

M-A=N

Here is an example.

The equation above means that the atomic number (A) subtracted from the average atomic mass (M) equals the combined amount of neutrons and protons. Since we know that 35 17Cl is Chlorine (this is because Chlorine (Cl) is the 17th number on the periodic table and has the average atomic mass of 35), we can insert our data into the equation and end up with the following:

35-17=18.

From here, we can tell that we have a mix of neutrons and protons, with the total being 18. Since the atomic number is 17, we can reasonably assume that there are 17 protons and 1 neutron.

But we still need to find the number of electrons. Fortunately, the number of electrons is always equivilant to the number of protons and the atomic mass, so we know that the number of electrons is 17.

So, we have;

17 Protons

1 Neutron

17 Electrons

Susan is investigating physical changes. To do this, she places some ice into a large bowl and seals it with a lid. She leaves the bowl on the counter for several hours until all of the ice has melted. Using a balance, Susan determines that the mass of both the water and the ice are equal. Why is the mass of the ice and the water the same? (SC.8.P.9.1)

Answers

Answer:

No mass loss

Explanation:

The mass of ice and the water in the different state are equal because the same of quantity of matter is present in both state of matter of matter.

In essence, the mass of the physical change process is conserved. When mass is conserved, matter is neither created nor destroyed but can be changed from one form to the other. This is in compliance with the law of conservation of matter. So, no mass was lost in the physical change process and the mass will remain the same.

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?

Answers

Answer:

The correct answer is - rain.

Explanation:

At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.

At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.

Thus, the precipitation is in the form of rain.
