Considering that both sodium (na) and cesium (cs) are both alkali metals, which of the following is a correct description of their relative ionization energy? a) cesium has a lower ionization energy because it will form an anion. b) cesium has a higher ionization energy because it is smaller. c) sodium has a higher ionization energy because it is smaller. d) sodium has a lower ionization energy because it will form an anion. ~i'll give top 5 stars + guys c'mon its important so no spammers.~

- C) sodium has a higher ionization energy because it is smaller.

Explanations:- Ionization energy is the energy required to remove electron from valence shell of an atom in it's gaseous form.

More energy is required to remove the electron if the size of the atom is smaller as it's electrons are more tightly attracted by it's nucleus.

In periodic table, atomic size decreases on moving left to right in a period and increases on going top to bottom in a group.

Na and Cs are the elements of same group(first group) and also Cs is below Na. So, as Na is placed above Cs, the size of Na is smaller than Cs and so more energy is required to remove the electron from this smaller atom.

hence, the right choice is C) sodium has a higher ionization energy because it is smaller.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
