An element is a substance composed of atoms with identical atomic number . The older definition of element (an element is a pure substance that can't be decomposed chemically) was made obsolete by the discovery of isotopes .
Atom raqamlari bir xil bo'lgan atomlardan tashkil topgan modda. Elementga berilgan avvalgi ta'rif (element bu kimyoviy bo'linmas toza modda) izotopning kashf qilinishi bilan o'z kuchini yo'qotdi.
A chemical change in which one compound aquires H+ from another. The compound that receives the hydrogen ion is the base; the compound that surrenders it is an acid.
Bir birikma boshqa birikmadan H+ qabul qilib olgandagi kimyoviy o'zgarish. Vodorod qabul qiluvchi birikma asos, beruvchi birikma kislota deyiladi.
Particle found in a nucleus with a positive charge. Number of these gives atomic number.
Yadroning musbat zaryadga ega tarkibiy qismi. Protonlar soni atom raqamiga teng.
A reaction where a substance loses electrons, called oxidation,
Modda elektronlarini yo'qotgan reaksiyalarga oksidlanish reaksiyalari deyiladi.
Enthalpy (H) is defined so that changes in enthalpy ( H) are equal to the heat absorbed or released by a process running at constant pressure. While changes in enthalpy can be measured using calorimetry, absolute values of enthalpy usually cannot be ...
Entalpiyaning ta'rifiga ko'ra, uning o'zgarishi bosim doimiy bo'lgan holatda yutilgan yoki ajratilgan issiqlikka tengdir. Entalpiyaning o'zgarishlar oralig'ini kalorimetr yordamida o'lchash mumkin bo'ls-da, uning mutlaq qiymatini o'lchash mumkin emas. ...
A substance that is made up of two or more chemically bonded elements.
Ikki yoki undan ortiq kimyoviy bog'langan elementlardan tashkil topgan modda.
Massless packet of energy, which behaves like both a wave and a particle.
O'zini ham to'lqin, ham zarracha sifatida namoyon qiluvchi massasiz energiya to'plami.
A process that absorbs heat. The enthalpy change for an endothermic process has a positive sign.
Issiqlik yutilishi bilan boradigan jarayonlar. Endotermik jarayon uchun entalpiya ko'rsatkichi musbat bo'ladi.
cations -ions that has a positive charge, and anions are those having negative charge
Kationlar - musbat zaryadga ega ionlar, anionlar esa manfiy zaryadga ega ionlardir.
A subatomic particle with a net charge that is negative.
Atomning manfiy zaryadga ega qismi.
