Answer:
O by increasing atomic number
Explanation:
Elements are arranged on the periodic table by increasing atomic number.
The atomic number of an element is the number of protons in such an atom. These protons are the positively charged particles in the atom.
Every atom of an element has a unique number of protons that distinguish it from other atoms.
Based on the number of protons which is the atomic number, elements are arranged on the periodic table.
Aluminium metal will readily react with water at room temperature to form aluminium hydroxide and hydrogen
Answer:
C.) They have fewer electrons than protons
Explanation:
Charges on ions are determined by the ratio of electrons to protons. Neutral elements have the same number of protons and electrons. Remember: protons have a positive charge and electrons have a negative charge. However, based on the amount of electrons these elements have, some are more or less willing to give up their electrons to participate in ionic bonding. Potassium usually gives up 1 electron because this satisfies the octet rule. By removing this electron, the element has more protons than electrons, giving it an overall +1 charge.
