Question
Determine which statements are true of neutral magnesium atoms.They have 12 electronsThey have an equal number of protons and neutronsThey have an equal number of protons and electronsThey have more neutrons than protons
Solution
-
"They have 12 electrons" - This statement is true. Neutral magnesium atoms have 12 electrons.
-
"They have an equal number of protons and neutrons" - This statement is false. Magnesium atoms have 12 protons and typically 12 neutrons, but isotopes may have more or fewer neutrons.
-
"They have an equal number of protons and electrons" - This statement is true. In a neutral atom, the number of protons (positive charge) and electrons (negative charge) are equal, balancing each other out to make the atom neutral.
-
"They have more neutrons than protons" - This statement is generally false. Most magnesium atoms have an equal number of protons and neutrons, but some isotopes of magnesium may have more neutrons.
