Answer : 0.00684 kg is not equal to 0.0684 dkg.

Explanation :

The conversion used for mass from kilogram to dekagram is :

1 kg = 100 dkg

The conversion used for mass from kilogram to grams is :

1 kg = 1000 g

The conversion used for mass from kilogram to centigrams is :

1 kg = 100000 cg

The conversion used for mass from kilogram to milligrams is :

1 kg = 1000000 mg

Now we have to determine the same mass as 0.00684 kg.

(1) 1 kg = 100 dkg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 100dkg=0.684dkg$

(2) 1 kg = 1000 g

0.00684 kg = $\frac{0.00684kg}{1kg}\times 1000g=6.84g$

(3) 1 kg = 100000 cg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 100000cg=684cg$

(4) 1 kg = 1000000 mg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 1000000mg=6840mg$

Hence, from this we conclude that, 0.00684 kg is not equal to 0.0684 dkg.

Based on the position of the elements in the periodic table, what is the charge of the ions they are most likely to form?

Rainbow [258]

Explanation:

The charge on an ion denotes the amount of electrons lost or gained or even shared by an atom.

An atom will lose, gain or share an equal amount of electrons that will make it stable and achieve an octet and perfect configuration.

This is often synonymous with the component number of electrons in their outermost shell. The valence shell.

For metals on the periodic table, they are always willing to give up electrons due to their large electropositivity.

Metals will give up the number of electrons in their outermost shell to become stable.

Groups 1 and Group 2 will have charges +1 and +2 on them.

For non-metals , they will gain the exact number of electrons that will make them stable. We must note that half -filled and fully filled orbitals are equally stable.

Elements in groups 6 and 7 are electronegative and will have a charge of -2 and -1 respectively.

For those in groups 3, 4 and 5 they either gain, lose or share commensurate amount of electrons that will make them stable.

Group 8 elements are stable and have no charges.

Generally on the periodic table, metals are to the left and are always positively charged. Non - metals are to the right and are negatively charged.

group of atoms that gains or loses electrons is called _______. A. a polar ion B. a non-polar ion C. a polyatomic ion D. a commo

raketka [301]

Answer: Option (C) is the correct answer.

Explanation:

An ion is defined as a specie which is formed when a neutral atoms tends to gain or lose an electron.

When a neutral atom gain an electron then it forms a negative ion whereas when a neutral atom tends to lose an electron then it forms a positive ion.

For example, a neutral fluorine atom on gaining an electron will form $F^{-}$ ion. And, a sodium atom on losing an electron forms $Na^{+}$ ion.

When a group of atoms form ions then it tends to form polyatomic ions.

Thus, we can conclude that group of atoms that gains or loses electrons is called a polyatomic ion.
