LMBO, for science.

Answer:

<em>The increase in kinetic energy leads to leakage of water from the syringe. When the outside temperature is more than the liquid temperature, say the syringe is out in sunshine, then the liquid becomes slightly warmer.</em>

Without consulting Figure 28 or Table 22, determine whether each of the following electron configurations is an inert gas,a halo

Anna [14]

This is an incomplete question, here is a complete question.

Determine whether each of the following electron configurations is an inert gas, a halogen, an alkali metal, an alkaline earth metal, or a transition metal. Justify your choices.

(a) $1s^22s^22p^63s^23p^5$

(b) $1s^22s^22p^63s^23p^63d^74s^2$

(d) $1s^22s^22p^63s^23p^64s^1$

(e) $1s^22s^22p^63s^23p^63d^24s^2$

(f) $1s^22s^22p^63s^2$

Answer :

(a) $1s^22s^22p^63s^23p^5$ → Halogen

(b) $1s^22s^22p^63s^23p^63d^74s^2$ → Transition metal

(c) $1s^22s^22p^63s^23p^63d^{10}4s^24p^6$ → Transition metal

(d) $1s^22s^22p^63s^23p^64s^1$ → Halogen metal

(e) $1s^22s^22p^63s^23p^63d^24s^2$ → Transition metal

(f) $1s^22s^22p^63s^2$ → Alkaline earth metal

Explanation :

Inert gas : These are the gases which lie in group 18.

Their general electronic configuration is: $ns^2np^6$ where n is the outermost shell.

Halogen : These are the elements which lie in group 17.

Their general electronic configuration is: $ns^2np^5$ where n is the outermost shell.

An alkali metal : These are the elements which lie in group 1.

Their general electronic configuration is: $ns^1$ where n is the outermost shell.

An alkaline earth metal : These are the elements which lie in group 2.

Their general electronic configuration is: $ns^2$ where n is the outermost shell.

Transition elements : They are the elements which lie between 's' and 'p' block elements. These are the elements which lie in group 3 to 12. The valence electrons of these elements enter d-orbital.

Their general electronic configuration is: where n is the outermost shell.

(a) $1s^22s^22p^63s^23p^5$

The element having this electronic configuration belongs to the halogen family.

(b) $1s^22s^22p^63s^23p^63d^74s^2$

The element having this electronic configuration belongs to the transition family.

(c) $1s^22s^22p^63s^23p^63d^{10}4s^24p^6$

The element having this electronic configuration belongs to the transition family.

(d) $1s^22s^22p^63s^23p^64s^1$

The element having this electronic configuration belongs to the halogen family.

(e) $1s^22s^22p^63s^23p^63d^24s^2$

The element having this electronic configuration belongs to the transition family.

(f) $1s^22s^22p^63s^2$

The element having this electronic configuration belongs to the an alkaline earth metal.

Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization ene

Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization energy

The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.

The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.

H(g) -----> H+(g) + e- deltaHo = -1312.0 kJ/mol

Answer:

Explanation:

Question 1:

atomic number/number of protons

All atoms of the same element share the same number of protons or atomic numbers. In grouping elements on the periodic table, the periodic law is often used. The modern periodic law states that "properties of elements are a periodic function of their atomic number". The atomic number of an element distinguish it from others.

Question 2:

The two carbon atoms would be quite different as they are isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

Naturally, carbon exists in two isotopic forms:

¹³₆C and ¹⁴₆C

One might see these different samples in a rock and in the skin cells. They are simply isotopes. Isotopes have the same electronic configuration and hence similar chemical properties. Only their masses differ.
