Question

13 fill in the blank 1 point an anion is a charged ion. 14 numeric 1 how many protons does na+ have? answer 15 fill in the blank 1 point what is the chemical name of the atom with 11 protons 12 neutrons and 11 electrons?

Explanation:

• For question 13: An anion is formed when an atom gains electrons. Electrons are negatively - charged particles. So, an anion has more electrons than protons and is negatively charged.
• For question 14: The atomic number of sodium (\(Na\)) is 11. The atomic number is equal to the number of protons in an atom. When \(Na\) forms \(Na^{+}\), it loses an electron, but the number of protons remains the same as in the neutral atom.
• For question 15: The number of protons determines the element. An atom with 11 protons has an atomic number of 11. The element with atomic number 11 is sodium.

Answer:

1. negatively
2. 11
3. sodium
