In this video we will write the electron configuration for Ca2+, the Calcium ion. We’ll also look at why Calcium forms a 2+ ion and how the electron configur. The total electron configuration is: 1s22s22p63s23p64s2 or Kr4s2 The valence electrons are found in the highest energy level of the electron configuration in the 's' and 'p' orbitals. In the case of calcium this is 4s2.

Explanations

1 Which statement describes the charge and location of an electron in an atom?

(1) An electron has a positive charge and is located outside the nucleus.

(2) An electron has a positive charge and is located in the nucleus.

(3) An electron has a negative charge and is located outside the nucleus.

(4) An electron has a negative charge and is located in the nucleus.

3electrons...negative...outside nucleus

protons....positive...in nucleus

2 Which statement explains why a xenon atom is electrically neutral?

(1) The atom has fewer neutrons than electrons.

(2) The atom has more protons than electrons.

(3) The atom has the same number of neutrons and electrons.

(4) The atom has the same number of protons and electrons.

4neutral...postive equals negative

protons equal electrons

3 If two atoms are isotopes of the same element, the atoms must have

(1) the same number of protons and the same number of neutrons

1definition of atomic mass
Calcium

A model of calcium shows 20 protons. Most calcium atoms have 20 neutrons (although this can vary). The shells surrounding the nucleus contain the electrons, which have a negative charge. Bohr model is an early model of atomic structure in which electrons circulate around the nucleus in discrete stable orbits with different energy levels.
