Polonium Word Search
This Polonium word search hides 12 words on a 15×15 grid — the terms and ideas of a school subject. Trace each one with a finger or mouse and it locks in as soon as the whole word is covered. No signup, no download.
Words to find: POLONIUM, ELEMENT, PERIODIC, ATOMIC, NUCLEUS, PROTON, NEUTRON, ELECTRON, IONIZATION, ISOTOPE, RADIOACTIVE, RADIOACTIVITY.
Found words stay highlighted, so the grid gets easier to read as you go and the final few tend to fall quickly.
Polonium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- POLONIUM /pəˈloʊniəm/ · noun
- Polonium is a rare, highly radioactive chemical element with the symbol Po and atomic number 84. It has no stable isotopes, and its radioisotopes are studied chiefly for their extreme radioactivity.
- ELEMENT /ˈɛlɪmənt/ · noun
- A fundamental or essential part of something larger; in chemistry and physics, a substance consisting of atoms all with the same atomic number that cannot be broken down into simpler substances by ordinary chemical means. Related: component, constituent, ingredient, factor.
- PERIODIC British /ˌpɪə.rɪˈɒd.ɪk/; US /ˌpi.əˈrɑː.dɪk/ · adjective
- Occurring at regular intervals or according to a recurring pattern; cyclical. In technical contexts, it can also mean relating to a recurring cycle, especially in mathematics, science, or chemistry. Related: regular, recurrent, recurring, cyclical.
- ATOMIC /əˈtɒmɪk/ · adjective
- Relating to atoms, or to the energy or structure of atoms. More broadly, describing something that is divided into very small, discrete units. Related: nuclear, minute, tiny.
- NUCLEUS /ˈnuːkliəs/ · noun
- A nucleus is the central, typically rounded part of an atom or biological cell, containing genetic material and playing a central role in the cell's activity. More broadly, the term refers to a central, fundamental, or defining part of something. Related: core, center, centre, heart.
- PROTON /ˈprəʊtɒn/ (British); /ˈproʊtɑːn/ (American) · noun
- A positively charged subatomic particle found in the nuclei of atoms. In South Asian English, the word can also mean a person who supports a proposal, policy, or candidate. Related: hydrogen-1 nucleus, positively charged baryon, hydrogen nucleus.
- NEUTRON /ˈnjuːtrɒn/ · noun
- A neutral, electrically uncharged subatomic particle found in the nucleus of an atom and having a mass slightly greater than that of a proton.
- ELECTRON /ɪˈlɛktrɒn/ · noun
- A stable subatomic particle with a negative electric charge, found in all atoms and moving around the nucleus. Electrons are the primary carriers of electricity in solids and are responsible for chemical bonding. Related: negatron, subatomic particle, charged particle, beta particle.
- IONIZATION /ˌaɪənəˈzeɪʃən/ · noun
- The process of converting atoms or molecules into electrically charged particles called ions, typically by removing or adding electrons. It may occur naturally, as in the ionization of gases by radiation, or be induced artificially, as in a gas discharge tube.
- ISOTOPE /ˈaɪsoʊˌtaʊp/ · noun
- An isotope is one of two or more forms of the same chemical element that have identical numbers of protons but different numbers of neutrons. Isotopes therefore have nearly identical chemical properties but different atomic masses and may differ in stability and radioactivity.
- RADIOACTIVE /ˌreɪ.di.oʊˈæk.tɪv/ · adjective
- Having unstable atomic nuclei that spontaneously emit ionizing radiation. Informally, extremely exciting, intense, or dangerously attractive.
- RADIOACTIVITY /ˌreɪ.di.oʊ.ækˈtɪv.ə.ti/ (US); /ˌreɪ.di.əʊˈæk.tɪv.ə.ti/ (UK) · noun
- The spontaneous decay of unstable atomic nuclei, accompanied by the emission of ionizing radiation such as alpha particles, beta particles, or gamma rays. Related: radioactive activity, radioactive decay.
