Question

1. does a given element always have the same number of each particle? why or why not? using a periodic table, give some specific examples. a given element will have the same protons but not neutrons or electrons

Explanation:

Elements are defined by the number of protons. Isotopes of an element have the same number of protons but different numbers of neutrons. Ions of an element have different numbers of electrons. For example, carbon - 12 and carbon - 14 are isotopes of carbon. Both have 6 protons, but carbon - 12 has 6 neutrons and carbon - 14 has 8 neutrons. Sodium (Na) has 11 protons in its neutral state. When it forms a sodium ion (Na⁺), it loses 1 electron.

Answer:

No, a given element always has the same number of protons, but can have different numbers of neutrons (isotopes) and electrons (ions). For example, carbon - 12 and carbon - 14 are isotopes of carbon with different neutron numbers, and sodium can form Na⁺ ions with a different electron number than neutral sodium.
