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.

Answer:

eight

Because the noble gases are the least reactive of all elements, their eight valence electrons are used as the standard for nonreactivity and to explain how other elements interact.

Explanation:

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.

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.

Explanation:

Answer:

The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen.

Explanation:

:))

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]

[tex]\text{New overall average speed}=25+2.5[/tex]

[tex]\text{New overall average speed}=27.5[/tex]

Therefore, the new overall average speed is 27.5 cm/s.

Answer:

i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

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.

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

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

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

Q = m.c.Δt

m= mass, g

c = heat capacity, for water : 4.18 J/g° C.

ΔT = temperature

Q= 140 J

Δt = 75 - 60 = 15

mass of the water :
