Question

atoms, or atomic ions or isotopes, are made of subatomic particles: protons, neutrons and electrons. electrons surround the nucleus and are negatively charged particles with almost no mass. protons and neutrons, at the center of the atom, do have mass. protons are positively charged particles, while neutrons are neutral.in most atoms, the number of electrons and protons are the same, balancing the atoms electrical charge. sometimes, however, a few of the electrons can become shared with another atom. this creates a new molecule called a compound. compounds have the atoms of different elements.hydrogen bromide is a chemical compound. its formed from atoms of hydrogen and bromine, twochoose one optiona electronsb elementsc neutronsd nuclei

Explanation:

1. For the first multiple-select question: Compounds are formed by atoms of different elements bonding, so the correct statement is "Compounds have the atoms of different elements."
2. For the second single-select question: The text states atoms are made of protons, neutrons, and electrons. The options list these subatomic particles, and electrons are the negatively charged particles surrounding the nucleus as described.

Answer:

1. Compounds have the atoms of different elements.
2. A. electrons
