Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. In three to five sentences, identify the direction of the change, and give two reasons for the change.

Question

Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. In three to five sentences, identify the direction of the change, and give two reasons for the change.

Please help! I don't understand the question.

Answer 1

The question is asking about the change in reactivity when moving from the element with atomic number 10 (neon) to atomic number 11 (sodium) on the periodic table. Reactivity refers to how readily an element can undergo a chemical reaction. In this case, the change in reactivity is an increase in reactivity. Two reasons for this change are:

1. Atomic Structure: Sodium has one more electron in its outermost energy level compared to neon. This extra electron makes the outermost electron shell less stable in sodium, allowing it to easily lose this electron and become more reactive.

2. Electronegativity: Neon is a noble gas and has a full outer electron shell, making it stable and less likely to react with other elements. Sodium, on the other hand, has a lower electronegativity and a strong tendency to lose its outermost electron, which results in increased reactivity.

Answer 2

Of course! The question is asking about the change in reactivity when moving from the element with atomic number 10 (neon) to atomic number 11 (sodium) on the periodic table. To answer it, you need to consider the general trend in reactivity across the periodic table. Reactivity tends to increase as you move from right to left and from top to bottom on the periodic table. In this case, moving from neon (group 18, right side) to sodium (group 1, left side) means moving towards higher reactivity. Two reasons for this change in reactivity could be the decrease in the number of valence electrons and the larger atomic size, both of which contribute to an increased tendency to lose an electron and form positive ions.

Answer 3

Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. In three to five sentences, identify the direction of the change, and give two reasons for the change.
