Which of the following contains the most atoms?
24.305 g Mg
39.098 gk
21.62 g B
9.0122 g Be

Answers

Explanation:

9.0122 g be Maybe, sorry i don't think so

In the above , the sample of B 21.62 g of boron contains the most atoms because it has approximately 2 moles, while the other samples have only 1 mole each.

What is atoms

The molar mass of each element can be found on the periodic table.

The molar mass of Mg (magnesium) is about 24.305 g/mol.The molar mass of K (potassium) is about 39.098 g/mol.The molar mass of B (boron) is approximately 10.81 g/mol.The molar mass of Be (beryllium) is about  9.0122 g/mol.

To calculate the number of moles in each sample, we divide the mass of each sample by its respective molar mass:

For Mg: Number of moles = 24.305 g / 24.305 g/mol = 1 moleFor K: Number of moles = 39.098 g / 39.098 g/mol = 1 moleFor B: Number of moles = 21.62 g / 10.81 g/mol ≈ 2 molesFor Be: Number of moles = 9.0122 g / 9.0122 g/mol = 1 mole

Therefore, the sample with 21.62 g of boron (B) contains the most atom

Imagine you are a scientist who has just discovered a new element. The element has an atomic number of 113, and it has three elections in the outer energy level of each atom.
Which element would have properties most similar to the new element?
Group of answer choices

A.boron
B.carbon
C.hydrogen
D.beryllium

What would you name this new element?

Answers

Answer:

3 valence electrons

The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons. The valence electrons are the electrons found in the highest energy level in the s and p orbital.

Explanation:

Nihonium has to be the #113 element of the periodic table

A. is the correct answer because Boron has 3 electrons too,

All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.

Boron element would have properties most similar to the new element. Therefore, option (A) is correct.

Why do the elements of same group have similar chemical behavior?

The chemical properties of elements depend on the number of valence electrons in their valence shell. Elements in the same group in the modern periodic table have the same number of valence electrons. Therefore, chemical elements situated in same group of the modern periodic table have similar chemical behavior.

The chemical elements having an identical outer electronic configuration in their atoms are placed in the same group of the periodic table. These valence electrons of an element are responsible chemical behavior and reactivities of the elements.

Therefore, both Boron and a new element with atomic number 113  have three electrons in their valence shells. So they belong to the same group and will have similar chemical properties.

Choose the electron configurations which are possible for an unexcited atom. Example 1 – 1s22s22p4 Example 2 – 1s22s22p63s23p33d1 Example 3 – 1s22s22p83s1 Example 4 – 1s22s22p63s1

Answers

Answer:

Examples 1, 3 and 4

Explanation:

An unexcited atom is an atom in the ground state i.e the atom has it's valence electrons in it's lowest energy level possible. This actually implies the normal electronic configuration of the atom. Thus, examples 1, 3 and 4 have the actual electronic configuration with there valence electrons in the lowest possible energy level.

Example 1: 1S² 2S² 2P⁴

Example 3: 1S² 2S² 2P⁶ 3S¹ (There seem to be a mistake in the question provided, P energy level can only 6 electrons not 8)

Example 4: 1S² 2S² 2P⁶ 3S¹

NOTE: If you take a look at example 2, it will be deduced that the 3P energy level has only 3 valence electrons and the last valence electron jumped to 3d energy level; making that atom appear to be in it's excited state.

Explain in your own words what the law of conservation of mass means

Answers

Answer:

Mass can neither be created nor destroyed in a chemical equation, it  transfer from one to another form.

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Which element below would have a 3+ charge as an ion?

Answers

Answer:

Al3+

Explanation:

Aluminium has an electronic configuration of 2, 8, 3 and the outermost valence electrons is +3 since it is a metal

Elements acquire positive or negative charges by losing or gaining electrons. The element which have 3+ charge among the options is boron (B) Hence, option B is correct.

What is boron?

Boron is 5th element in periodic table and it is classified into 13th group. Boron is a metalloid and shows properties intermediate to metals and non metals.

The electronic configuration of boron is K =2, N =3. Atoms lose or gain electrons as per their valency to become stable. According to octet rule atoms become stable when their valence shell get completely filled.

Boron have 3 electrons in its valence shell. If it donate these three electrons into an electronegative atom, its K shell become its valence shell and it is completely filled. Thus boron becomes stable.]

When atoms loses electrons they acquire positive charge and this charge is numerically equal to the number of electrons lost. Thus boron acquire 3 unit of positive charge by donating its 3 electrons. Hence, option B is correct.
