Question

the current model of the atom is known as
rutherfords model
bohrs model
planetary model
electron cloud model
question 14
atomic mass is the sum of
metalloids and metals
neutrons and electrons
protons and electrons
protons and neutrons
question 15
most elements on the periodic table are
metalloids
gases
non - metals
metals

Explanation:

• For the first question, the current model of the atom is the Electron - Cloud Model as it describes the probability of finding an electron in a certain region around the nucleus.
• For the second question, atomic mass is the sum of protons and neutrons since electrons have negligible mass compared to protons and neutrons.
• For the third question, most elements on the periodic table are metals as they occupy a large portion of the table.

Answer:

• First question: Electron Cloud Model
• Second question: protons and neutrons
• Third question: metals
