Пошаговое решение:

• Первый пропуск: 'worked' (работал). Менделеев работал как великий химик.
• Второй пропуск: 'arranged' (упорядочил). Он упорядочил периодическую классификацию элементов.
• Третий пропуск: 'graduated' (окончил). Менделеев окончил Главный педагогический институт.
• Четвертый пропуск: 'discovery' (открытие). Его открытие было связано с зависимостью свойств элементов.
• Пятый пропуск: 'to establish' (установить). Он был первым, кто установил зависимость свойств элементов от их атомного веса.
• Шестой пропуск: 'ordering' (упорядочивая). Он упорядочил элементы по их атомному весу.
