- 7. Able to be hammered or pressed permanently out of shape without breaking or cracking, commonly used to describe metals.
- 8. Mass The average mass of an element's atoms, typically expressed in atomic mass units (amu), taking into account the relative abundance of isotopes.
Down
- 1. A horizontal row in the periodic table of elements, indicating the number of electron shells in the atoms of the elements.
- 2. A vertical column in the periodic table, where elements in the same group have similar chemical properties and the same number of valence electrons.
- 3. Number The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
- 5. Key A section of information on the periodic table that shows essential data about an element, such as its atomic number, symbol, atomic mass, and sometimes its state of matter.
- 6. Electron The electron(s) in the outermost shell of an atom that determine how the atom interacts with other atoms in chemical reactions.
