When a potassium atom loses an electron, it obtains a positive charge and becomes a potassium ion (K +). It goes as follows: K → K + + e - . Therefore, carries a positive charge.
The chemical element with the atomic number 19 and the letter K is potassium. Potassium is a silvery-white metal that may be easily and gently sliced with a knife. Within seconds of exposure, potassium metal quickly combines with air oxygen to produce flaky, white potassium peroxide.
Many significant chemicals are formed by potassium. The most prevalent potassium compound is potassium chloride (KCl). It is used to make other compounds, a salt alternative, and fertilizers.
Vegetables, fruit, potatoes, meat, bread, milk, and nuts all contain potassium. It aids neuronal activities and plays a significant part in the human body's fluid system. 95% of the potassium in the body is found inside cells, where it congregates as the ion K+.
Thus, When a potassium atom loses an electron, it obtains a positive charge and becomes a potassium ion (K +).

If it loses 1 electron, it will now have 1 more proton than electrons.
Thus, the charge would be 1+

Answer:
Explanation: The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables.
Correct answer=
gold is an element, it has a symbol of An
Hope it helped
Gold is an element, not a compound or a mixture. It is represented on the periodic table by the symbol Au and cannot be broken down into a simpler substance.
Gold is an element, not a compound or a mixture. It's one of the 118 known chemical elements, and it's represented on the periodic table by the symbol Au (from the Latin 'aurum'). As an element, gold consists of only one type of atom and cannot be broken down into a simpler substance. It differs from a compound, which is formed from two or more elements bonded together, and a mixture, where you can physically separate the individual components that make it up.
