21. When considering the Bohr model of a neon atom, which of the following is a true statement?
Ten protons would be located in the nucleus, and 10 neutrons would be on the outside of the atom orbiting in rings.
Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
O Ten protons would be located in the nucleus, and 20 neutrons would be on the outside of the atom orbiting in rings.
OTwenty protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
Answers
The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.
The extension to atoms with more than one electron in the last shell the model results are not completely correct.
The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.
In the case presented of Neon, its electronic configuration is
1s² 2s² 2p⁶
Let's examine the different claims:
a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.
b) True. The protons are in the nucleus and the electrons are in circular orbits.
c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.
c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .
In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

negative ions form when atoms _______ valence electrons.
Answers
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

Explanation:
Getting to the equation:Calcium in water reacts vigorously to give a cloudy white Precipitate (compound) called Calcium hydroxide alongwith the evolution of Hydrogen gas.
[tex] \boxed{ \mathsf{Ca + H_2O \rightarrow Ca(OH)_2 + H_2}}[/tex]
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Balancing the equation:This reaction is not in it's balanced form! The number of atoms of Hydrogen on the left is 2 while that on the right is 4,I.e.,they're not equal.
Adding a 2 in front of H2O solves the problem by making the number of atoms of each element on both the sides equal.
[tex] \mathsf{Ca +2 H_2O \rightarrow Ca(OH)_2 + H_2}[/tex]
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Observations:Looking into the equation more carefully, we see:
1 atom of Calcium reacts with 2 molecules of water to give 1 molecule of Calcium Hydroxide alongwith 1 molecule of Hydrogen gas.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Gram atomic and molecular massesMass of one atom of Calcium = it's gram atomic mass
= 40 g
Mass of one "molecule" of Hydrogen
= it's Gram molecular mass
= gram mass of one atom × number of atoms in one molecule
= 1 × 2
= 2 g
So,
according to our observation:
One atoms of Calcium gives one molecule of Hydrogen (during the particular reaction)
=> 40g of Calcium gives = 2g of Hydrogen
•°• 1 g of Calcium gives = [tex] \frac{2}{40} [/tex]
= [tex] \frac{1}{20} [/tex] g Hydrogen
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Answer:We're provided with 20g of Calcium,
=> 20g of Calcium gives = 20 × [tex] \frac{1}{20} [/tex] g H2
= 1 g H2

A student wants to calculate the heat gained of 100 grams of water in order to
calculate the specific heat of a metal in the following problem. The water is
heated from 25C to 50C when the metal is added. The specific heat of water is
4.18 J/gºC. Use Q=m xCxT*
Answers
The quantity of heat gained to raise the temperature from 25.0°C to 50.0°C is 10,450 Joules.
Given the following data:
Mass of water = 100 gramsInitial temperature = 25.0°CFinal temperature of water = 50.0°CSpecific heat capacity of water = 4.18 J/g°CTo find the quantity of heat gained:
Mathematically, heat capacity or quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the heat capacity or quantity of heat.m represents the mass of an object.c represents the specific heat capacity.∅ represents the change in temperature.Substituting the values into the formula, we have:
[tex]Q = 100(4.18)(50 - 25)\\\\Q = 418(25)[/tex]
Quantity of heat = 10,450 Joules.

An atom is electrically neutral when...
O The number of protons and neutrons are equal.
O The number of protons and electrons are equal.
O The number of neutrons and electrons are equal.
O The neutrons balance the protons and electrons.
Answers
Answer:
The number of protons and electrons are equal.
Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
