Question

Define
1. Isotopes. 2. electrovalent Bond.
3. atomic number

Answer 1

Answer:

yes

Isotopes are the atoms of the same element which have different mass number is called

isotope

during the formation of electrovalent aur ionic compound the number of electrons lost or gained by one atom of an element to achieve the nearest noble gas electronic configuration is called the electron Bond

the number of protons in one atom of an element is called atomic number of that element

Answer 2

Answer:

1. Isotope : each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element

2.Elecrovalemt bond : a chemical bond formed between ions of opposite charge. — called also ionic bond

3. Atomic radius : The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. ... Electrons do not have definite orbits, or sharply defined ranges.
